Most of Frankfurt’s medieval Jewish ghetto, situated along narrow Judengasse (Jews’ Street), was destroyed by a French bombardment in 1796, but you can get a sense of local Jewish life during the 15th to 18th centuries from the excavated remains of houses and ritual baths. Laws confining Frankfurt’s Jews to the ghetto were repealed in 1811. Following renovations, the museum here is due to reopen in 2016.
