Old Synagogue

The Alte Synagoge in Erfurt, Germany, is one of the best preserved medieval synagogues in Europe, its oldest parts dating back to the late 11th century. Most parts of the building date from around 1250–1320. It is thought to be the oldest synagogue building intact to its roof still standing in Europe.Since 2009 it has been used as a museum of local Jewish history. It houses the Erfurt Treasure, a hoard of medieval coins, goldsmiths' work and jewellery found in 1998.
