The Abbey of St. Martin, established in 1124 in Laon in northern France, was one of the earliest foundations of the Premonstratensian Order. Along with Cuissy Abbey and Floreffe Abbey it counted as one of the primarii inter pares, or senior houses, of the order.
The Premonstratensian community was founded by Barthélemy of Jur, bishop of Laon, in co-operation with Saint Norbert of Xanten, who settled it with twelve canons from Prémontré Abbey. It took over the site of an earlier college of canons regular, established in the Carolingian period, which had fallen into decay.
It was dissolved in the French Revolution. The church of St. Martin in Laon, dating from mid to late 12th century, is still in use as a parish church. The former monastic buildings were converted into a hospital in 1810.
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.
