At about 40m long, Carlungie Earth House is one of the largest and most complex examples of its kind in Scotland. It was accidentally discovered during ploughing in 1949. Subsequent excavations during the following two years also revealed about eight associated stone dwellings at ground level.
Earth houses, or souterrains as they are also known, were not dwellings, but stone-lined underground passages which typically date to the Iron Age. They’re found along much of eastern Scotland, as well as in Ireland, Cornwall and Brittany.

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.
