Craignethan Castle is a ruined castle in South Lanarkshire, Scotland. Built in the first half of the 16th century, Craignethan is recognised as an excellent early example of a sophisticated artillery fortification, although its defences were never fully tested.
Craignethan is built on an imposing site above a bend in the River Nethan. Steep slopes protect the castle on the south, north and east sides, but the castle is actually overlooked by higher ground to the west, making it far more vulnerable than it appears. Craignethan's defences are therefore concentrated towards the west. The castle comprises a low central keep, within a rectangular walled courtyard. To the west is a deep ditch and beyond, a larger outer courtyard. The rectangular keep measures 21m by 16m, and was originally of two storeys plus an attic.

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.
