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 Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
