An-Nasr Mosque, Religious building in Nablus, Palestine

An-Nasr Mosque stands in the central square of Nablus's Old City and is known as the "symbol of Nablus". Its prayer hall occupies the second floor of the building and is covered by a turquoise dome. The 1935 reconstruction gave the mosque a new structural design on the site of an earlier Crusader church.

An-Nasr Mosque stands on the site of a Byzantine church that the Crusaders replaced with a small circular church topped by a red dome. After Saladin took Nablus in 1187, the Mamluks converted the Crusader church into a three-nave mosque. An earthquake destroyed it in 1927, and the Supreme Muslim Council under Amin al-Husayni rebuilt it in 1935 with a new design, supervised by Shaykh Amr Arafat.

The mosque is known as the "symbol of Nablus" and gives its name to Bab al-Saha, the square in the Old City where it stands. Its imam has traditionally been of the Hanafi school. The ground floor holds historic tombs, and tradition holds that the site is where Jacob was brought Joseph's bloodied coat.

Islamic tradition holds that an-Nasr Mosque stands on the exact spot where Jacob's sons brought him Joseph's "bloody and tattered coat". The building also carries medieval masonry marks recorded in 1896 by Charles Simon Clermont-Ganneau, who noted exterior buttresses. The 17th-century Ottoman traveller Evliya Çelebi described it as "formerly a large monastery" and remarked on its uncommon garnet-coloured columns.
