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.

Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
