A Jewish community is typically characterized by the presence of a synagogue, a mikve (ritual baths) and a cemetery. The synagogue was often located close to the castle, such as in Vienna or Klosterneuburg. In Vienna the main building in the Jewish quarter was the synagogue. Very close by was the hospital, from where a door lead to the synagogue. The hospital was used not only for the sick and aged, but also to accommodate visitors spending the night in Vienna.
The ritual baths (mikveh) was another common facility. One existed in 1314 at the entrance to the Jewish quarter. A "Tukhaus" (mikve) was located right on the Judenplatz itself. The two large baths in front of the Kaerntnertor and in Kleeblattgasse were probably used for recreation. They were acquired only in 1370 by the Jewish community so that it is likely that before that many Jews had visited baths used by Christians. The community also had a slaughterhouse and a cemetery. All these facilities were found only in large communities, such as Krems and Wiener Neustadt. In smaller places, Jews lived together in the same street, such as in St. Veit, or sometimes shared a house such as in Lienz.
