The Abbey of Saint-Michel-en-l'Herm dates from 682 AD when it was constructed by Benedictine monks from Noirmoutier. It was destroyed by Vikings in 877 AD. The new church was completed in 1047.
In 1569, Protestants attacked it, killing approximately 200 monks. The motives for the attack are still debated, but one theory is that the attackers sought treasure and manuscripts hidden by the Bishop of Luçon.
The final destruction took place during the French Revolution when the abbey was confiscated and most of buildings destroyed.
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.
