Law, permission and reporting are separate duties

Before any archaeological digging

Section 23 of the Manx Museum and National Trust Act 1959 makes it an offence to dig or excavate in or under any land in search of archaeological objects unless the work is carried out under a licence granted by the Trust.

Landowner permission and an archaeological licence answer different questions. Permission from an owner does not replace the Manx National Heritage licensing requirement.

Metal detectors in protected areas

Section 21A of the 1959 Act prohibits using or knowingly permitting the use of a metal detector in a protected area without the Trust’s written consent. The Act defines the relevant protected-area regime; do not infer designation or access from a pin on this site.

Written consent under section 21A is distinct from the section 23 excavation licence and from landowner permission. One does not silently confer the others.

The 14-day reporting duty

Section 20 of the 1959 Act requires the discovery of an archaeological object to be reported to the Trust within 14 days. Manx National Heritage is the operating name of the Manx Museum and National Trust.

Section 8 of the Treasure Act 2017 separately requires a person who believes, or has reasonable grounds for believing, that an object is treasure to notify the Trust within 14 days after discovery. After the Trust receives the object, section 9(2) requires it to notify the Treasury and the Coroner of Inquests. The finder’s statutory first notification is therefore to the Trust, not directly to the Coroner.

The 14-day rules concern reporting after discovery. They are not a grace period and do not authorise searching, detecting, digging, removal, damage or access.

Wreck is a separate route

Finds from ships or aircraft in Manx territorial waters are covered by separate wreck legislation and should be reported to the Isle of Man Receiver of Wreck. A map coordinate is not a diving or navigation instruction.

If you encounter a possible archaeological object

1. Stop work and leave the surrounding context undisturbed.
2. Record what was visible without cleaning, altering or widening the find spot; note the date and take context photographs only if safe and lawful.
3. Contact Manx National Heritage promptly. Do not wait until the end of the 14-day period.
4. For wreck material, also follow the Isle of Man Receiver of Wreck route.
5. Do not publish a precise findspot while heritage staff are assessing it.
