End-on view of the barrier (on the left and carrying main road between St Margaret's Hope and Kirkwall) that joins Lamb Holm to Glims Holm, From where this picture was taken Lamb Holm is where the famous Italian Chapel is situated - you can't miss it.&amp;nbsp; It was built by Italian POWs otherwise employed on the Churchill Barriers. Note also - centre of pic - the remains of the blockships sunk here to protect the channel before the barriers were built.&amp;nbsp;
