The report "Jewish Historic Monuments and Sites in Bulgaria" published by The United States Commission for the Preservation of America's Heritage Abroad in 2011 states:
"Probably built in the early 20th century, the smaller Ashkenazi synagogue is characteristic of Central European Art Nouveau. After the Second World War, until the beginning of the 1990s when it was reclaimed by the Jewish community, it was used as a Judo club. Recently, the building has been remodeled on the inside for offices and rented for income. The exterior has been restored to its original appearance."
