In 2014 the mikveh was identified in the patio of the Museum of Jewish History. The original structure has been preserved even though in later rebuildings it was transformed into a cistern. It was a closed space which could be accessed by a door, leading to a hall, a tiled changing room and the pool. Access was gained by stepping over the threshold, which led to a landing made of stone slabs, and from there people could probably go into the pool through a flight of stairs integrated in the pool, now lost. The water was supplied from a natural source by filtration, and also from the tank situated in the courtyard, which collected rainwater and filled the bath. The function of the mikveh is the spiritual purification through total immersion of the body in the water.
