There are the remains of an Irish round tower on the edge of the Armoy village. An early monastery was founded about AD 460 by Saint Olcán, a disciple of Saint Patrick. The only trace of an early monastery is the stump of the round tower, which stands in the grounds of St Patrick's Parish Church. The tower is about 11 m high and has three storeys. At one time, Armoy was the main religious settlement in the Irish part of the kingdom of Dál Riata.
The Temple of Edfu is one of the best preserved ancient shrines in Egypt. It was built in the Ptolemaic Kingdom between 237 and 57 BC.
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.
