There has been an ironworks in Jädersbruk since Middle Ages. It was originally owned by Julita Abbey. After Reformation Jädersbruk was confiscated to the Crown. King Gustav Vasa set up there the first arms manufactory “Arboga faktori, Jäders Bruk” to decrease the dependence of foreign weapons.
Weapons fere forged until the end of 17th century when the ironworks gradually started manufacturing of civilian products. The ironworks flourished until the early 20th century. Today the manor house and workers’ cottages remain and there are art and handicraft workshops.
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.
