In Roman times, the city was named Tarraco and was capital of the province of Hispania Tarraconensis (after being capital of Hispania Citerior in the Republican era). The Roman colony founded at Tarraco had the full name of Colonia Iulia Urbs Triumphalis Tarraco. Augustus wintered at Tarraco after his Cantabrian campaign, and bestowed many marks of honor on the city, among which were its honorary titles of Colonia Victrix Togata and Colonia Julia Victrix Tarraconensis. There are still many important ancient remains at Tarragona. Like most other ancient towns which have continued to be inhabited, remains has been pulled down by its own citizens for the purpose of obtaining building materials. The amphitheatre near the sea-shore has been used as a quarry. Throughout the town Latin, and even apparently Phoenician, inscriptions on the stones of the houses proclaim their previous use. Tarragona is home to a large port and the Universitat Rovira i Virgili.
