Salt Island, Anglesey
Coordinates: 53°18′58″N 4°37′26.5″W / 53.31611°N 4.624028°W Salt Island (Welsh: Ynys yr Halen) is an island joined to Holy Island, itself an island joined to Anglesey in North Wales. It is a natural provider of shelter for the town's Old Harbour from the Irish Sea and is also part of the Port of Holyhead where the ferries to Dublin sail from.
The island gained its name by a factory located on it which processed sea water in order to extract sea salt. By the early 18th century the sea salt was often mixed with rock salt (often smuggled onto the island) to increase the quality of the factory's product. The factory ceased production in 1775.
Another building no longer standing on the island was the Stanley Sailor's Hospital. This hospital was set up in 1871 by a local philanthropist and initially only treated sailors although it quickly became a general hospital. It was taken over by the National Health Service in 1948 and closed its doors in 1987.
There have been three lighthouses located on the island. The current lighthouse is the Holyhead Mail Pier Light.
