The site of the early medieval chapel and burial ground of St Mary's, or Keeill Worrey, thought to have been in use between AD500 and AD1000.  The site was excavated by R. Lace in 1910. 


The chapel measured 7.3 metres by 3.65 metres and its north wall stood up to 1.2 metres high as recently as 1860. Seven lintel graves were revealed at the east end of the keeill at a depth of 0.30 metres.  The total number of graves found at the keeill was seventeen; three of which lay outside the keeill. Human remains were retrieved in only two of the excavated graves. Similar graves were also found in widening the entrance to the farm north of the keeill.


No visible trace remains of the chapel or of the burial ground enclosure and the site is now occupied partly by a driveway and partly by a lawn.
