The Ponts Couverts are a set of three bridges and four towers that make up a defensive work erected in the 13th century on the River Ill in the city of Strasbourg in France. The three bridges cross the four river channels of the River Ill that flow through Strasbourg's historic Petite France quarter. The Ponts Couverts have been classified as a Monument historique since 1928.
Construction of the Ponts Couverts commenced in 1230, and they were opened in 1250. As a defensive mechanism, they were superseded by the Barrage Vauban, just upstream, in 1690, but remained in use as bridges. As built, each of the bridges was covered by a wooden roof that served to protect the defenders who would have been stationed on them in time of war. These roofs were removed in 1784, but name Ponts Couverts (covered bridges) has remained in common use ever since.

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.
