Public monument
A visitor monument with a public point. It is not an export licence or a protected-area boundary.
Uncertainty area
A broad area around a historic context. The circle is uncertainty, not a place to collect objects for removal.
Withheld findspot
A modern find whose location an official source keeps confidential. The atlas adds no geometry and no export status.
Rule without a pin
A statutory restriction discussed for what the Act requires, not for where an object was found.
A symbol is not permission
This article explains section 21 of the consolidated Manx Museum and National Trust Act 1959, the 2023 Manx National Heritage archaeology guide, and the enacted Treasure Act 2017, all checked on 14 October 2026. It is not legal advice. It does not grant access, an export licence, detecting consent, an excavation licence or permission to remove, sell or dig. Only a licence issued by the Trust can authorise the removal and export acts in section 21. If you find a possible archaeological object, leave the surrounding context undisturbed and contact Manx National Heritage before moving it off the Island.
Answer first: removal needs a Trust licence
Section 21 of the Manx Museum and National Trust Act 1959, in the consolidated text checked on 14 October 2026, is the restriction on export of archaeological objects. It does not fold every journey off the Island into one casual phrase. It names three acts. The first is removing an archaeological object from the Island to the United Kingdom. The second is exporting an archaeological object from the Island to a country outside the United Kingdom. The third is selling an archaeological object for such removal or export. Each is an offence if it is done without a licence issued by the Trust under section 21(2), or otherwise than in accordance with that licence. A licence that exists on paper does not cover a journey, a destination or a sale that departs from its conditions.
The Trust is the Manx Museum and National Trust. Section 3(2) says the Trust may continue to perform its functions under the name Manx National Heritage, Eiraght Ashoonagh Vannin. A licence under section 21 is issued by the Trust, at the Trust's discretion. This atlas cannot issue one, predict one, or treat a conversation, a landowner's agreement or a document from outside the Island as that licence. The tests for what counts as treasure, and the announcements about particular declared finds, are separate questions and are handled in other journal guides. This guide is about leaving the Island with an archaeological object, or selling it so that someone else can.
United Kingdom, beyond it, and sale
The split inside section 21 matters for anyone who treats the Island as a trip from the United Kingdom. Removal to the United Kingdom is its own limb. The section does not describe it as a lesser form of export, and it does not say that a short trip, a private collection or a plan to bring the object back later falls outside the offence. Export to a country outside the United Kingdom is the second limb. The Act uses those two destination phrases. It does not list ports, airlines or ferry routes, and this guide does not add any. What the text requires is a licence for the act itself, followed in accordance with that licence.
The third limb is sale. A person can commit the offence by selling an archaeological object for removal to the United Kingdom or for export outside it, even where the seller is not the person who carries the object. The section does not publish a price, a market or a class of buyer that is exempt. Subsection (2) describes the licence the Trust may issue: a licence to remove an archaeological object from the Island to the United Kingdom, or to export it from the Island to a country outside the United Kingdom. The Trust may attach such conditions and restrictions as it thinks proper. This guide does not invent a standard condition, a standard duration or a form of wording. Where a sale is for that removal or export, it avoids the offence only when it is in accordance with a licence issued under that subsection. The statute does not say that every sale of an archaeological object, with no removal or export in view, is this offence.
Which objects the export rule uses
Section 21 uses the Act's definition of an archaeological object, not a casual meaning of find, souvenir or treasure. In the consolidated text, an archaeological object means any chattel, including ancient human and animal remains, whether manufactured, partly manufactured or unmanufactured, which by reason of the archaeological interest attaching to it, or of its association with any Manx historical event or person, has a value substantially greater than its intrinsic value, and that intrinsic value includes artistic value. The same definition says that, notwithstanding section 30, the expression includes all treasure. Section 30 is the Crown rights section. It is not a list of objects that may be taken off the Island. The inclusion of treasure means an object that is treasure is an archaeological object for this Act. It does not mean that only treasure is covered, and it does not decide a borderline object by itself.
The 2023 Manx National Heritage guide, Archaeology on the Isle of Man, makes a practical point that belongs beside the definition and should not be collapsed into it. It says the Island's definition of an archaeological object differs from definitions elsewhere in the British Isles, that it includes all treasure, and that it includes human remains when recovered by archaeological excavation. The offence text remains the consolidated definition, including the interest and value test. The guide's sentence about human remains is the guide's practical statement. This article does not decide whether a particular bone, coin or fragment meets the test. That is a question for the Trust and, where treasure is in issue, for the process in the Treasure Act. What counts as treasure under section 4 of the Treasure Act 2017 is set out in the journal on that definition. This export guide does not repeat those metal, age and significance tests.
Reporting is not a window for travel
Section 20 is the reporting duty for an archaeological object, and it is not permission to leave with the object while the days run. A person who finds an object they believe, or have reasonable grounds for believing, is an archaeological object must notify the Trust before the end of the notice period and permit the Trust to inspect, examine or photograph the object. The notice period is 14 days beginning with the day after the object is found or, if later, the day the finder first believes or has reason to believe the object is an archaeological object. The notification must include the finder's name and address, the nature and character of the object, the time, place and circumstances of finding, and any other information the Trust requests. Failing to report, or giving information the person knows is false or misleading in a material respect, is a separate offence under section 20. The 14 days are a deadline for telling the Trust. They are not a period set aside for packing an object into luggage.
If the person believes, or has reasonable grounds for believing, that the object is treasure, section 8 of the Treasure Act 2017 adds its own duty to notify the Trust. Section 8(7) says that duty does not limit section 20 of the 1959 Act. Both notifications can therefore be in point, and neither is a section 21 licence. Where a treasure notification has been made, section 9 says the person must, if the Trust requires it, deliver the object as the Trust directs. When the Trust receives it, the Trust must give a receipt and an image and notify the Treasury and the coroner. The 2023 guide states the practice for treasure in one line: the objects are deposited at the Manx Museum while the treasure process takes its course. That practice is not a general permission to remove other objects, and it is not a reward, a valuation or a promise that the finder may later take the object off the Island. This guide states no reward amount. The rewards provisions are explained in the definition journal, not here.
How the heritage guide states the rule
The 2023 guide puts the practical warning in a single sentence: no archaeological object can be altered, damaged or taken off the Island without a licence from Manx National Heritage. Read that sentence against the Act, not instead of it. Taken off the Island is the guide's compression of the removal and export limbs in section 21. Altered and damaged point at section 22, which is a different licence and a different offence. The guide also says no archaeological excavation can take place without first obtaining a licence from Manx National Heritage. That is section 23, again a different power. Using the guide's sentence as if one licence covered alteration, damage, excavation and export would go beyond both the guide and the Act.
The same guide gives a contact for further information and advice: iomher@mnh.im, the telephone numbers +44 (0)1624 648025 and +44 (0)1624 648026, and Manx National Heritage in Douglas. Those details were on the guide checked for this article. Use the current official page if they have changed. The guide also keeps underwater finds on a separate route. It says any finds of wreck within the 12 mile Manx territorial waters limit must be reported to the Island's own Receiver of Wreck. This article does not decide whether a particular wreck object is also an archaeological object for section 21. Wreck reporting, and the way this atlas frames coastal records, are explained in the journal on coastal wrecks and inland sites. A section 21 question about an object from the shore or the sea still starts with the Trust, not with a guess from a map pin.
Export is not the digging or detector rule
Section 22 prohibits injuring, defacing or destroying an archaeological object. It also prohibits altering an archaeological object otherwise than under and in accordance with a licence granted under that section. The Trust may issue a licence to alter a specified object in a specified manner, to a specified extent, and subject to specified conditions. An export licence under section 21 is not that alteration licence. Cleaning, marking, repairing or otherwise changing an object is a section 22 question. Carrying it to the United Kingdom, or selling it so that it can be carried, is a section 21 question. They can both apply to the same object. Satisfying one does not, on the face of these sections, state that the other has been given.
Section 23 prohibits digging or excavating in or under any land, whether or not the surface is removed, in search of archaeological objects or for another archaeological purpose, unless the work is under a licence from the Trust. The Trust may limit that licence to specified land, specified purposes, conditions and restrictions. Section 23(4) says the section does not make agricultural or industrial operations unlawful, and that a licence under the section does not make lawful anything that would be unlawful if the section had not been passed. An excavation licence is therefore not a quiet answer to the export offence. Section 21A is different again. It restricts use of a metal detector in a protected area without the Trust's written consent, and it separately restricts removal, without that consent, of an object of archaeological or historical interest discovered by a metal detector in a protected area. That removal sits in section 21A. It is not the section 21 removal from the Island to the United Kingdom. In section 21A a protected area is the site of an ancient monument, or of a monument in the Trust's ownership or guardianship under the Act, or a place in an area the Trust has designated by order as of archaeological importance for that section. This atlas does not show which places are protected areas. Written consent, an excavation licence, landowner permission and a section 21 licence answer different questions.
Penalties, discretion, and the atlas
Section 21 states the maximum on summary conviction for the export offence: imprisonment for a term not exceeding six months, or a fine not exceeding £5,000 or a sum equal to two times the value of the goods, whichever is the greater, or both. Those are maxima in the consolidated text. They are not a prediction of what a court would do, and this guide is not a sentencing note. The footnote in that consolidated text records that section 21 was substituted by the Manx Museum Act 1984. Use the consolidated PDF if the offence wording is needed. The Trust's power in section 21(2) is discretionary. The Act does not require the Trust to issue a licence, and it does not list a class of finders who must receive one. Silence from this website is not a decision of the Trust.
Manx Treasure Map does not record export licences, alteration licences or excavation licences against its places. A marker is a public feature reference. A circle is an uncertainty area. A withheld record is a decision to publish no geometry. None of those treatments is a licence to remove an object, sell it for export, or dig. Where an official source withholds a modern findspot, this article adds no point and no area. The place-page guide explains how to read a record without treating it as a target. For the statutory meaning of treasure, use the definition journal. For finds an official announcement has already described as declared treasure, use the declared-treasure journal. Before any removal from the Island, the document that matters is a licence issued by the Trust under section 21, read with its conditions, together with the reporting duties if the object has just been found.

Questions readers ask
Marker, circle and withheld-location FAQ
Can I take an archaeological object from the Isle of Man to the United Kingdom?
Section 21(1) of the 1959 Act makes removal from the Island to the United Kingdom an offence when it is done without a licence issued by the Trust under section 21(2), or otherwise than in accordance with that licence. A plan to bring the object back, and a landowner's agreement, are not substitutes stated in the section. The section does not say that the licence is the only duty which can apply to an object.
Does selling a find for export need a licence as well?
Section 21(1) includes selling an archaeological object for removal to the United Kingdom or for export to a country outside the United Kingdom. The sale is an offence if it is without a licence issued under section 21(2), or otherwise than in accordance with that licence. The section does not set a minimum price. This guide does not decide whether a particular sale has that purpose.
Is treasure outside the Isle of Man export restriction?
No. The 1959 definition says the expression archaeological object includes all treasure. An object that is treasure is therefore inside the vocabulary section 21 uses. Whether a particular object is treasure is a separate question, decided through the Treasure Act process rather than by this atlas. The export licence and the treasure notification are different duties.
Does the 14-day reporting period allow the object to leave the Island?
No. Section 20 gives 14 days to notify the Trust of an archaeological object and to permit inspection, examination or photography. The Treasure Act adds its own notification duty where the finder believes the object is treasure, and that duty does not limit section 20. Neither period is a section 21 licence to remove the object from the Island.
Does this page or a map pin grant an export licence?
No. A licence under section 21 is issued by the Trust, at its discretion, and may carry conditions. A marker, a circle, a withheld record and this article do not issue that licence or grant access. The 2023 guide asks readers to contact Manx National Heritage for further advice, including at iomher@mnh.im.
