Harry Avery's Castle is situated half a mile south-west of Newtownstewart, Northern Ireland. It is a rare example of a stone castle built by a Gaelic Irish chief, although its origins and history are uncertain. It is associated with and named after Henry Aimhréidh O'Neill (died 1392), whose name was anglicised as Harry Avery.
The standing part of the castle comprises a two-storey rectangular construction fronted by massive D-shaped twin towers. Although having the appearance of a gatehouse, this structure was in fact a simple tower house with the D-towers added to the front. The tower comprised a vaulted basement entered from a large door between the D-towers. Above this was a hall on the first floor level, which was accessed from the courtyard. The southerly D-tower contained a spiral stair linking the two storeys, and both D-towers contained small rooms at first floor, with single windows in their round walls. Traces of a mural stair lead up from the first floor, and there is a latrine chute leading up, suggesting at least a parapet at the second floor. Examination of the structure suggests that it was built in a single phase, rather than being a modification of an older gatehouse.
The design of the castle has been compared to that of Elagh Castle, Inishowen, which also appears to have been a native-built castle featuring D-towers. The inspiration is thought have come from Norman castles such as Carrickfergus Castle and Castle Roche, both of which have true gatehouses flanked by D-towers. The overall design of Harry Avery's Castle is also similar to other Gaelic fortresses such as Seafin, County Down, which were later enclosed by a curtain wall with a tower house.

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.
