The Roman city of Teate was built on a hill between the Pescara and Allento rivers, on a site frequented since the protohistoric era. The town developed considerably in the 1st century BC, when it became a Roman municipality under the name of Teate Marrucinorum.
The most important archaeological remains, located in the public area of the city, are the Civitella, the theater, the thermal baths and the Roman temples.
In the archaeological area of Civitella terracotta, statues and decorations of the temples of the Republican age (I century BC) and an amphitheater of the I century AD were found
On the slopes of the Civitella hill are the remains of the Roman theater (1st century AD), incorporated into the city fabric; the perimeter wall of the cavea and some remains of the semicircular corridor on two levels can be distinguished.
At the eastern slopes of the hill stood the baths (2nd century AD), a vast complex with mosaic decorations, divided into various rooms and fed by the underground cistern facing the spa.
In the ancient forum the remains of the three Roman temples, of imperial age, stand out; on the site mosaic floors and square structures were found dating back to a more ancient place of worship.
