It is a two-story wood-frame structure, with a gabled roof and exterior finished in modern siding.

Its main facade, facing Concord Street, is dominated by projecting square towers at each corner, each with an onion dome at its top.

[5] The building was erected in 1906 for the Orthodox Beth Israel Congregation, which was organized in 1865 by German Jewish immigrants.

While the onion domes are an unusual detail, the architecture is otherwise within usual standards for synagogues in Connecticut.
