The Gates of Heaven Synagogue, also known as the Old Synagogue, is a historic synagogue in Madison, Wisconsin, United States, designed by German immigrant architect August Kutzbock and constructed in 1863 for the Gates of Heaven congregation. The congregation that commissioned the synagogue was a group of 17 German-speaking Jewish families that met within the building until financial difficulties obliged them to rent it to numerous tenants from 1879, until finally selling the building in 1916. The synagogue was then sold to a succession of owners, and was at various times a dentist's office, a funeral home, and the office of US Congressman Robert Kastenmeier.
In 1970, the synagogue was set to be demolished, but was spared for concerned members of the community to raise money to move the synagogue to a new site.
