The Bridge of Mantible (Puente Romano de Mantible) is a ruined bridge located near Logroño. According to some historians, construction of the bridge began in the first half of the 2nd century, well into Rome's imperial period. Others suggest that the bridge was built in the 11th century, near the same time in which the Puente La Reina was constructed over the River Arga, and that both were made to join the two most important cities of the Kingdom of Navarre, Nájera and Pamplona.
Neither theory makes clear at what point the bridge became no longer passable, but there are documents that suggest that it had already fully deteriorated by halfway through the 16th century.
The bridge is 164 meters long, 5 meters wide and reaches a maximum height of 30 meters. It was built with seven semicircular arches, only two of which stand relatively intact today. There are only a few remains of the other five arches. The two standing arches serve as an example of the excellent quarry stone used in the bridge.

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.
