A bathhouse that dates to the Byzantine period was exposed in an archaeological excavation undertaken by the Israel Antiquities Authority near Kibbut Gevim (at the site of Horvat Lasan) and underwritten by the Israel Railways, prior to laying a railroad track from Ashkelon to Netivot.
According to archaeologist Gregory Serai, director of the excavation on behalf of the Israel Antiquities Authority, “The bathhouse, which covers an area of 20 x 20 m, was apparently destroyed in a cave-in and was later used as a rubbish dump that was filled with household refuse. It was ascertained in the excavation that the furnace (hypocaust) was dug into the natural soil and its ceiling was built of a cement-like material that was lined with ceramic tiles. The ceiling was supported by means of one meter high colonnades built of mudbricks. The bathers entered the changing room (apodyterium) and passed from there into a room with cold water (frigidarium) where there were probably stepped tubs. From there they continued into the room with warm water (tepidarium) and on to the room with hot water (caldarium – comparable to today’s sauna). The floor of the caldarium was paved with marble flagstones, some of which were as big 1 x 1 m. Evidence of the ceiling’s destruction is attested to by the manner in which the hypocaust columns were toppled in different directions”.
