Rosslyn Chapel was founded on a small hill above Roslin Glen in the mid-15th century. The chapel was founded by William Sinclair, 1st Earl of Caithness of the Scoto-Norman Sinclair family.
After the Scottish Reformation (1560), Roman Catholic worship in the chapel was brought to an end, although the Sinclair family continued to be Roman Catholics until the early 18th century. From that time the chapel was closed to public worship until 1861, when it was opened again as a place of worship according to the rites of the Scottish Episcopal Church, a member church of the Anglican Communion.
Since the late 1980s, the chapel has also featured in speculative theories concerning a connection of Freemasonry, the Knights Templar and the Holy Grail. It was prominently featured in the 2003 bestselling novel The Da Vinci Code and its 2006 film adaptation. Numerous books were published after 2003 to cater to the popular interest in supposed connections generated by Brown's novel. The chapel, built 150 years after the dissolution of the Knights Templar, supposedly has many Templar symbols.
Rosslyn Chapel remains privately owned. The current owner is Peter St Clair-Erskine, 7th Earl of Rosslyn.
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.
