Isen Abbey was a Benedictine abbey, later a collegiate foundation. Dedicated to Saint Zeno of Verona, the abbey was founded by members of the Fagana family, an indigenous Bavarian noble clan, and by Bishop Joseph of Freising (also known as Joseph of Verona) in the 8th century, about 752. It was one of the oldest monasteries on ancient Bavarian soil. Until the beginning of the 12th century it was Benedictine, but afterwards became a collegiate foundation.
It was dissolved during the secularisation of Bavaria in 1802. The premises and the abbey's seven farms passed into private ownership, while St. Zeno's church, with a house for the priest, became the parish church of Isen.
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.
