The Erfurt Synagogue in Erfurt, Germany, was built c. 1100. It is thought to be the oldest synagogue building still standing in Europe. It is planned to permanently house the Erfurt Treasure and is currently undergoing renovation.
The oldest parts of the building date from the 11th century and the medieval building is preserved to a remarkable degree, including the roof. The building was used for purposes other than worship for many years. The Erfurt Small Synagogue was built in 1840 and was used through 1884. It was restored in 1998 and is an event venue. The building featured a Classically-influenced façade and interior. In 1884 the community constructed a magnificent Moorish Revival synagogue. It was destroyed on Kristallnacht. A New Synagogue was built in 1952. The New Synagogue was firebombed by a neo-Nazi group in April, 2000.
