Located in the Adige river valley, Trento, whose name probably derives from the three mounts (Bondone, Calisio and Marzola) that surround the town and which resemble a trident, became a Roman municipium between 50 and 40 b.C. The current historic centre is built directly on the remains of the Roman town, following the traditional design based on two main axis (cardo and decumanus). The relics discovered during recent excavations have shed light on the original town map. Castello del Buonconsiglio is one of the symbol of the city: it was built during the XIII century on a rocky hill close to the town walls and acted as seat of the Prince-Bishops of Trento until the secularisation of the Principality (1802). The Cathedral of San Vigilio was built in the XIII century on the ruins of the ancient basilica dedicated to San Vigilio; the left flank facing the square constitutes the main front due to the extensive and rich ornaments. Dominant elements are the door of the bishop, preceded by a vestibule and adorned by reliefs. The Abbey of San lorenzo is interesting too: it was built in the XII century by the Benedict monks from Bergamo and was one of the most frequented churches durinf the Council of Trent. Trento, in fact, host the homonymous Council (1545-1563) which represented a strong answer against Calvinism and Protestantism. It is a natural connection between the Italian and Central European cultures, a city full of arts which a rich historic heritage, as well as a Alpine city, where people live in close contact to nature: this is Trento!
