The 'Old Church' of Diekirch with its two naves in Gothic style, dates back to 1467. In the Merovingian period (6th and 7th centuries), a pre-Romanesque church was built in the place of a Gallo-Roman sanctuary, certain parts of whose walls are still visible today. In the 11th century, this building was replaced by a Romanesque church, whose tour has been kept (12th century). Inside, the church has fine frescoes dating from the 16th and 17th centuries. In 1960, a cemetery, probably from the Merovingian period, was discovered underneath 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.
