The Roman bridge of Salamanca crosses the Tormes River. Actually it is a construction of two separated bridges by a central fortification: the old bridge which extends along the portion near the city and it is of Roman origin, and the new bridge. Of the twenty-six arches, only the first fifteen date from Roman times. The bridge has been restored on numerous occasions and has survived several attempts demolition. Many of the restorations have been poorly documented, leaving for the study of archaeologists a great part of the work of determination, dating and explanation of the construction techniques of the ancient. The date of the construction of the bridge not is precisely known, but is among the mandates of the Emperors Augustus (27 BC-14 AD) and Vespasian (69-79), making it a bimillennium architectural monument.
The bridge is presented in the 21st century as a result of several restorations. One of the disasters that most affected it was the Flood of San Policarpo (January 26's night) of year 1626. From the construction of a third bridge for road traffic it remains a unique way of pedestrian and walking uses.

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.
