Lamb Holm is classified by the National Records of Scotland as an uninhabited island that "had no usual residents at the time of either the 2001 or 2011 censuses.
On the northwest of the island, on the shore of St Mary's Bay, are the remains of a prehistoric settlement which have been designated as a scheduled monument.
Of these, 550 were taken to Camp 60, where they were put to work building the Churchill Barriers, four causeways created to block unwanted extra sea accesses to Scapa Flow.
Since the prisoners' departure, several residents of Camp 60, including Chiocchetti, have made return visits to the chapel they created.
In 1996 a declaration was jointly signed by officials in Orkney and Chiocchetti's hometown of Moena, reinforcing the ties between the two places.
