The possible site of an early medieval chapel or keeill which would have been in use beetween circa AD500 and AD1000. It is said that a keeill formerly stood on the north side of the road about 100 metres west of Ballagonnell and was known as 'the Cabbal',  'Cabbal Vartin' , St Martins' or 'Keeill Columb'.  The foundations were removed and built into the parish church after 1865.


A clear glass annular bead with cylindrical perforation, now kept in the Manx Museum (Accession No. 1954-3874) is the only survivor of a series of beads found about 1870 in the course of levelling the keeill site.
