The first fort in Isein was built by bishop Atto of Freising in 784-811 AD. The current Burgrain castle dates from 1200s, when the lords of Burgrain built a four-winged building with keep and moat. The extensive additions and renovation was made in the 15th century by bishop Nicodemus.
After the secularization in 1804 Burgrain castle has been in possession of several owners. In 1906 it was converted into a home for blinds. Since 1919 it has been a private residence.
The castle church dates from 1719 and is richly decorated with rococo plasterwork.
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.
