Synagogue architecture

Synagogue architecture often follows styles in vogue at the place and time of construction. There is no set blueprint for synagogues and the architectural shapes and interior designs of synagogues vary greatly. According to tradition, the Divine Presence (Shekhinah) can be found wherever there is a minyan, a quorum, of ten. A synagogue always contains an ark, called aron ha-kodesh by Ashkenazim and hekhal by Sephardim, where the Torah scrolls are kept.

The ark may be more or less elaborate, even a cabinet not structurally integral to the building or a portable arrangement whereby a Torah is brought into a space temporarily used for worship. There must also be a table from which the Torah is read. The table, called bimah by eastern Ashkenazim, almemmar (or balemmer) by Central and Western Ashkenazim and tebah by Sephardim, where the Torah is read (and from where the services are conducted in Sephardi synagogues) can range from an elaborate platform integral to the building (many early modern synagogues of central Europe featured bimahs with pillars that rose to support the ceiling), to elaborate free-standing raised platforms, to simple tables. A ner tamid, a constantly lit light as a reminder of the constantly lit menorah of the Temple in Jerusalem. Many synagogues, mainly in Ashkenazi communities, feature a pulpit facing the congregation from which to address the assembled. All synagogues require an amud (Hebrew for "post" or "column"), a desk facing the Ark from which the Hazzan (reader, or prayer leader) leads the prayers.

A synagogue may or may not have artwork; synagogues range from simple, unadorned prayer rooms to elaborately decorated buildings in every architectural style.

The synagogue, or if it is a multi-purpose building, prayer sanctuaries within the synagogue, should face towards Jerusalem. Thus sanctuaries in the Western world generally face east, while those east of Israel face west. Sanctuaries in Israel face towards Jerusalem. But this orientation need not be exact, and occasionally synagogues face other directions for structural reasons, in which case the community may face Jerusalem when standing for prayers.
