During the 6th century AD a small community of monks settled on the Inishkeel island. Their religious leader was Saint Conall Cael, from whom the island later derived its name. During the following centuries Inishkeel was a traditional destination of pilgrimages. Remains of the church and the connected buildings as well as some carved stones can be seen on the island. For its artistical and archeological importance the island was declared National Monument. A bell known as St Conall Cael's Bell remained on Inishkeel up to the 19th century and was then acquired by the British Museum.
References:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
