⛰️ Tynwald Hill (St John's, 12ft artificial mound)

Not a natural hilltop but perhaps the MOST SIGNIFICANT elevated point on IoM. Tynwald Hill is an ARTIFICIAL ceremonial mound — the seat of the world's oldest continuously sitting parliament (established by Vikings, possibly earlier). Every July 5th for over 1,000 years, laws have been proclaimed from this tiered mound. The oldest maps show it as a key landmark. WHY FOR DETECTING: (1) 1,000+ years of annual gatherings = millennium of dropped items from wealthy attendees, (2) The FIELDS around Tynwald Hill hosted fairs, markets, and celebrations alongside parliament, (3) The processional route from St John's Chapel to the hill was walked by every important person on IoM, (4) The area was already significant before the Norse — pre-existing sacred landscape. Detect the FIELDS around the hill, not the hill itself (scheduled monument). The approach roads, the fair grounds, and surrounding farmland are the target.
