Medieval cross. This intricately carved wheel-headed cross slab (Manx Cross 73) is believed to stand in its original position, and is thus the only in situ example of a Manx cross. The church, also known as St Adamnan's Church or Lonan Old Church, and originally known in Manx as Keeill ny-Traie ('the chapel by the shore'), stands on a site whose oldest cross dates back to the 5th century AD. Around 1190 King Reginald granted land, likely including the church site, to St Bees Priory in Cumbria. An Act of Tynwald of 25 June 1733 authorised a new parish church at Boilley Veen, though it was not completed for another century, after which St Adamnan's fell into disuse. The Reverend John Quine, vicar from 1895, restored part of the building, and the Friends of St Adamnan's formed in 1968 to help maintain it; the church remains partly ruinous today.
