Järlåsa Church has had at least two predecessors. The earliest one was a medieval stone church whose ruins still remains c. 500 metres north of the church. At some point it was replaced with a wooden church, which was however in such a bad shape in the 17th century that it was replaced with the presently visible, octagonal church and demolished in the early 18th century.
The church may have been designed by Nicodemus Tessin the Elder; it was built at the initiative of Baron Gustaf Rosenhane, who is documented with having employed Tessin for other building projects. The main, octagonal church building was built 1672-1688 and inaugurated on 29 June 1688, while the church porch wasn't finished until 1704. Originally the sacristy was a wooden annex but it was replaced with a stone structure in 1766–68.
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.
