On the shores of the Mediterranean, right on the Costa Daurada, former Roman Tarraco offers us an important legacy of monuments amid extensive beaches. Its archaeological remains, forming a World Heritage Site, are one of the points of interest of this Catalan city. Tarragona, capital of Hispania Citerior during the Roman empire, preserves many buildings from this period. The walls surrounding the historic center were built in the 3rd century BC., although they were altered in the medieval period. Beside the sea stand the terraces of the Roman amphitheater which, in its day, (2nd C.), had capacity for more than 12,000 people. Here, they attended combats between gladiators and wild animals. The former Tarraco also had a theatre and a circus. The theatre, outside the walled enclosure and near the port, took advantage of the difference in levels in this area to build the terracing.
Tarragona´s historic city center features the Cathedral of Santa Tecla (patron saint of the city), a building built on the Roman temple of Augustus. Also belonging to the Middle Ages are the arcades of the Calle Mercería, although the Calle de Cavallers is considered the main street of medieval Tarragona. In this central part of the city, the Casa del Degà, Casa dels Concilis and Casa de la Ciutat are the outstanding features.
