Fehtija Mosque is a mosque and former Catholic church located in the town of Bihać, Bosnia and Herzegovina. Built in 1266, it is the oldest gothic building in the country. It was originally built as a Catholic church dedicated to Saint Anthony of Padua, and was subsequently transformed into a mosque following the 1592 conquest of Bihać from Habsburg Croatia by the Ottomans. The building was originally accompanied by a monastery, which was also mentioned in a 13th-century charter of the Croatian nobility.

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.
