Agricultural excavations at the site, conducted by KKL-JNF under Dr. Eli Shenhav in conjunction with the Israel Antiquities Authority, revealed large pools once used for bathing, and the aqueducts that channeled water into them. Handsome mosaics decorated the floors of the pools, and an impressive Roman theater was also uncovered. These large pools were situated behind the stage, and the spectators could see them from their seats. A statue of Neptune, the Roman god of the sea, was also found, and surgical instruments and gold coins were discovered in rooms at the site.
In the Byzantine period, however, Shuni fell out of favor. The theater seats were destroyed and replaced by industrial equipment, including a large olive press, most of which can still be seen on display at the site. Later, in the 12th century CE, the site was fortified by the Crusaders.
The building that occupies the site today was built in the 18th century, during the period of Ottoman rule. Because its rooms make use of the arches that once supported the theater seats, the structure is shaped like a half-moon. A number of rooms were also built in the aisles, and a wall was constructed around the stage.
