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.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
