It is a former Jewish Quarter of Prague named after the emperor Josef II, who freed Jewish people from the ghetto. The Jewish Quarter was established as early as 13th century and was separated from the Old Town by a wall.
Jewish people were rarely allowed to leave their quarter and often suffered from pogroms and other antisemitic practices. There are six original synagogues that survived WWII in Prague Jewish Quarter, such as Old New Synagogue, Spanish Synagogue and Pinkas Synagogue. Most of them work as museums and are available for visits. There is also the Ceremonial Hall and the Old Jewish Cemetery, which surprises people by its uneven terrain. You can visit it through the Prague Jewish Museum. It is opened from Sunday to Thursday from 9 am till 4 pm. The museum closes early on Friday and is closed completely on Saturday due to Sabbath.
