The Protestant church of Boazum or Saint Martin’s church is a late 12th century Romanesque church with inner walls of brick and outer walls of tuffstone with a 13th-century tower. It was built out of yellow and red brick. The choir is likely the oldest part of the building. The church was originally a Roman Catholic temple dedicated to Saint Martin, becoming a Protestant church after the Protestant Reformation.

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.
