The church of Saint-Pierre d'Andenelle with its tower dates from the 12th century. Built of reddish sandstone, this remarkable monument of Mosan architecture is one of the oldest in the region. It underwent alterations in the 17th century (the inside pillars were changed), in 1853 (the entrance portal, which used to be found in the north, was moved to the west), in 1860 (building of the transept), in 1875 (the portal was moved to the north as a result of the building of the Andenne-Haillot road) and in 1923 (building of the side aisles). It is a mistake to believe that it was built in a hollow. In times past, it was level with the road and the square. People entered on a level, through a big door at the foot of the tower, next to the stream. But when the Haillot bottom road was built, the portion of the road was raised and people had to go down a few steps to enter the church.

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.
