Medieval chapel.


The Ordnance Survey First Edition 1:2500 map records 'Chapel Gate, Site of St Mary's Chapel & Burial Ground (Keeill Moirrey) at SC20836806, without a marker defining the site. The chapel dedication gives its name to the moden settlement of Port St Mary.


The Manx Archaeologyical Survey (1968) notes that Speed's map of the Isle of Man, publised in 1605 (surveyed by Durham in 1595) includes a conventional pictogram labelled 'Chappell' on the shore of 'Portell Morrey' which would appear to indicate the keeill-site.


The Survey draws a comparison with Keeill Catreeney (PRN 0028), suggesting that the chapel must have stood close to the shore; no physical remains, however, have ever been recorded.
