just to the west of the coastguard but are best reached by going east a few yards below the lookout post and then doubling back by scrambling down an easy gully. The area below is scared with the ruins of an old RAF radar station which was bombed during the 2nd World War when 2 soldiers died when the cook house was hit. An emergency phone is located on the side of the coastguard hut now used by "Coast Watch" a voluntary organization.

The chapel, named after St. Aldhelm who was the Bishop of Sherborne and died in 709 AD, may have been built as a warning to sailors who were traversing what is certainly a dangerous part of our coastline. The cross on the roof could have been a bell or beacon to warn sailors below, but evidence is lacking.

It has been considered St. Aldhelm's Chapel was in fact a lookout disguised as a religious building. That possibility is perhaps negated by it's lack of openings. Something that is suspicious however is the orientation which is North-East, South-West etc., where churches and chapels tended to be orientated East, West, etc., for spiritual reasons. This relied on it being architecturally possible, and in this case there is nothing to prevent it. If there were an earlier earthwork with no particular orientation the chapel may of course follow it for convenience.
