It is not exactly known when the Abbaye de Sainte-Trinité in Lessay was established; other historians date it to 1056, Cologne University to 1105. The vaults of the church, built around 1100 are however probably the oldest in Normandy. The abbey flourished in the 12th and 13th centuries, but during the Hundred Years' War in 1356 it was burned and looted. The nave and tower were badly damaged and restored in 1385. Lessay Abbey suffered again in the French Wars of Religion, when it was looted twice. Again in World War II the bombings of Normandy invansion in 1944 destroyed it partially and restoration took 12 years.
References:The abbey was not bombed in 1944 but was deliberately blown up by German land mines before the Germans retreated.
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.
