Zion Synagogue, Plovdiv
The synagogue of Zion is, together with that of Sofia, the only synagogue still used as such in Bulgaria. According to archaeological studies, there was a synagogue in the city as early as the reign of Emperor Severus Alexander in the first half of the 3rd century. This synagogue would have been rebuilt several times until the beginning of the 5th century. In 1493, Aragonese Jews built a synagogue called "K. K. Aragon", which existed until 1540. After the Bulgarian independence, the construction of the modern synagogue in 1886 - 1887 started. The synagogue is one of the best preserved examples of the so-called "Ottoman style" synagogues in the Balkans.
