The Tarragona (called Tarraco in Roman times) Archaeological Site was declared a World Heritage site by UNESCO, as it is a unique record of the Romans in the Mediterranean. Tarraco was extremely important in the development of the Roman Empire's town planning, as it was the model to be copied by other provincial capitals in the empire.
Among the Roman remains that can be visited are the city walls, and monuments such as the amphitheatre, circus, and what is left of the forum. The city also holds the Roman and Paleochristian necropolis, one of the most important in Europe, and whose many discoveries are exhibited in the Tarragona Archaeological Museum.
The UNESCO site also includes the area for imperial worship and the provincial forum. The former can be found in the fine archaeological remains in the cathedral cloister. The latter are found in the buildings of the Antigua Audiencia, in Plaza Pallol square, in the Forum and the Praetorium.
Part of the Tarraco archaeological site is outside the city of Tarragona. These include the aqueduct, the sepulchre of the Scipios' Tower, the El Mèdol Quarry, the towns of Centelles (in the municipality of Constantí), and Els Munts (in Altafulla), and the Arch of Bará (in Roda de Bará).
