Clunia boasted two public baths, a basilica, a forum, many taverns and shops,a theater, and a large temple dedicated to Jupiter.

[2] Years later, the city was formally founded ex novo during the time of Emperor Tiberius, as part of the Roman plan to pacify the region after the Cantabrian Wars.

Nevertheless, it does not appear that there was a violent and general destruction; in any event, this preludes the end of the Roman cultural influence in the city of Clunia and its surroundings.

[1] Some limited reconstruction took place during the reigns of Diocletian and Constantine, but large parts of the city were uninhabited by the 7th century, during the Visigothic era.

[1] The full conquest of Visigothic Hispania by the Muslims, the city and its surroundings were conquered by the troops of the Berber general Tariq ibn-Ziyad during the year 713.

The excavations permitted the discovery —after centuries of being hidden— a theater excavated into rock, various domus with mosaics, streets, ruins of the buildings of the forum and a great cloaca, just as important sculptural findings, like an effigy of Isis and a torso of Dionysus, which are preserved at the National Archaeological Museum of Spain and in that of Burgos, including a large quantity of coins, epigraphic ruins, Roman ceramics such as Samian ware, glass and bronze objects.

The archaeological excavations have permitted the following of the evolution of the domestic town planning and verify some of its most characteristic features.

In the archaeological deposit, the following buildings can be observed: The most significant ruin is the theater, one of the largest of its time in Hispania, it was excavated into rock, and had a capacity of 10,000 spectators.

In Clunia, the forum is not very far from the theater, in whose environs the ruins of three domus stand out, a basilica and a macellum (market).

In the subsoil of the city, where no visiting is allowed due to its fragility, are the very interesting systems of water supply and a priapic sanctuary.
