San Nicolás church was built in the 12th century not only with religious functions, but also as a defensive bastion of the quarter during the strife with the neighbouring ones of St. Saturnino and Navarrería. The military role is evident in the watch tower. In 1222 the original Romanesque church was destroyed by a fire, and was replaced by a new building, consecrated in 1231.
The interior is in Gothic style, from different phases. It houses a Baroque organ. Exteriorly, of the Gothic period only two portal are visible today, as well as the apse. The corner portico was designed by Angel Goicoechea and built by a local contractor Blas Morte in the 1880s.
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.
