Ellis Island
During and immediately following World War II, Ellis Island was used to hold German merchant mariners and "enemy aliens"—Axis nationals detained for fear of spying, sabotage, and other fifth column activity. In December 1941, Ellis Island held 279 Japanese, 248 Germans, and 81 Italians removed from the East Coast. Unlike other wartime immigration detention stations, Ellis Island was designated as a permanent holding facility and was used to hold foreign nationals throughout the war. A total of 7,000 Germans, Italians and Japanese would be ultimately detained at Ellis Island. It was also a processing center for returning sick or wounded U.S. soldiers, and a Coast Guard training base. Ellis Island still managed to process tens of thousands of immigrants per year during this time, but many fewer than the hundreds of thousands per year who arrived before the war. After the war, immigration rapidly returned to earlier levels.
St Helen's, Isles of Scilly
St Helen's () is one of the fifty or so uninhabited islands in the archipelago of the Isles of Scilly and has an approximate area of . On the south side of the island is one of the earliest Christian sites in Scilly, an early medieval religious complex, which is thought to be the remains of St Elidius Hermitage, an 8th-century chapel lived in by Saint Lide, (also known as Elid or Elidius). There are also the remains of an isolation hospital used to quarantine sailors with plague. The island is the major part of a Site of Special Scientific Interest and some features have been given the designation of scheduled ancient monument. Access to the island is through chartered or private boat, although there are some season trips throughout the summer. St Helen's is currently managed by the Isles of Scilly Wildlife Trust.
