The ground floor contains exhibits pertaining to synagogue rites. The restored interior of the old Romaniote Synagogue of Patras can be found here.

Three of the nearby displays contain silver holy objects and valuable embroidered textiles, used to decorate the synagogues or mark their different architectural parts.

A special display contains traditional cylindrical wooden cases (tikkim) for the Scrolls of the Torah (Pentateuch), which are typical of the Romaniote Greek-Jewish tradition.
