The largest and most famous of the pre-World War II synagogues in Bardejov is the Old Synagogue. Begun in 1829 and completed in 1836, it is the oldest building of the Jewish Suburbia. Reflecting architectural features of the Baroque and Neo-Classical styles, it is one of two remaining nine-bay synagogues in Slovakia (along with the synagogue in Stupava) and is considered one of the most valuable examples of synagogue architecture in the country.
The Old Synagogue had been in great disrepair and used as a storage place for the merchandize of a plumbing and hardware business until it was empties in 2010. At that time some structure repairs to the roof and windows were performed as well as minor restoration of the ceilings.
In November 2014, the EEA and Norway Grants awarded 617,000 Euros to UZZNO for the restoration of the Old Synagogue in the Suburbia.
Restoration works began in the spring of 2015 and progressed rapidly. The Synagogue was officially opened to the public on June 2017.
