Clunia Sulpicia was founded in the 1st century BC by Emperor Tiberius. It had an area of 200 hectares, of which many villas, monuments, thermal baths and the theatre are still conserved. The forum was rectangular and there were two temples and an administrative building there. Three-storey houses and one of the largest theatres in Roman Hispania have been found. Pottery, mosaics, sculptures, glass and pieces of jewellery have also been discovered. One of the most important features of this city is the fact that there were Christian symbols, which means that one of the first Christian communities in the Iberian Peninsula might have lived in Clunia.
