Construction ended sometime between 13 and 11 BC. The theater was built of stone, concrete and brick and its exterior walls are made of white travertine stone.
One of the most beautiful elements of the theater was that it faced the river, turning the river into an integral part of the setting. Later in history, the theater became a fortress and then a residence. Today the site is a concert site and can accommodate 15,000 viewers.
During the summer months you can enjoy concerts held here every evening, in the magical and romantic atmosphere of this theater.
