The Citadel of Calais was built between 1560 and 1571 on the site of a former medieval castle which was built in 1229 by Philippe de Hureprel. Its purpose of its construction was to fend off would-be invaders, but it wasn't long until the city was successfully invaded by Archduke Albert of Austria on 24 April 1596. Both Louis XIII and Cardinal Richelieu at one time considered expanding the citadel and Calais into a great walled city for military harbour purposes but the proposals came to nothing.

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.
