A Synagogue had been constructed in ancient Philippopolis dating back to the reign of Emperor Alexander Severus in the first half of 3rd century AD, It is followed by several renovations, the last one – from the beginning of 5th century .In 1360, when the city was conquered by the Turks certain Jews who emigrated from Aragon in 1492 settled in Philippopolis and built a synagogue called "K. K. Aragon," which was standing in 1540, but is no longer in existence. In 1892[1] following Bulgaria liberation from Ottoman domination in 1878 one of the first synagogues to be erected was the (Zion) Synagogue in Plovdiv. It was built in the remnants of a small courtyard in what was once a large Jewish quarter called Orta Mezar during the Turkish rule. The Synagogue is one of the best-preserved examples of the so-called "Ottoman-style" synagogues in the Balkans.
