Little is known about the history of the city until Roman times. Selinus became Roman in 197 BC. With it began a brisk building activity. The growing demand for fresh water led to the construction of a water pipe, which led the water over long distances via an aqueduct into the city. Some parts of this aqueduct have been preserved, some of them hardly recognizable as such. This water pipe made it possible to build a large bath.
The destruction of the aqueduct also ended the function of the spa. The building fell into disrepair and served different purposes in the following centuries.
