Hi Dave,
The Churchill Barriers (4 in total) were built during WW2 after a German Sub got through the blockship barrier to enter Scapa Flow and sank the Royal Oak with the loss of many hundreds of lives.  Churchill brought about the building of 4 barriers linking Islands to the south of the Orkney Mainland to prevent such a thing being repeated.  Much of the work was carried out by Italian POWs, who also built the World famous Italian Chapel.  Eventually roads were constructed on the barriers so you can now travel from Holm to Burwick which previously had to be done by boat.  I'm sure Johnny will chime in with more info - don't think he (or Churchill) helped build them though!
