Erected in honour of Apollo, the present name of the city "Great" is derived from "Grannus", the other name given to the God of the Sun. An important religious city, at the beginning of our era the city was home to tens of thousands of inhabitants. Fallen into oblivion in the Middle Ages, due to its distance from the trade routes of the time, its remains were only rediscovered in the 19th century.
In the heart of the city, discover first of all the Grand museum with the flagship piece of the remains: one of the most colourful and extensive mosaics in Europe. Discovered in 1883 and restored in 2009, this 232 square metre work of art represents geometric drawings, animals or, in its centre, a theatre stage. Ornamentation of a church, a house of a rich dignitary or public monument...: doubts still remain as to the function of the building in which it rested.
