The Borderland Centre occupies Sejny's large synagogue, originally built by the sizable local Jewish community in the 1880s. During the German occupation the synagogue served as a fire station, and after the war as a storage room. Today it's an art gallery featuring the arts and culture of the region's various ethnic and religious traditions. In summer, the foundation regularly hosts evenings of klezmer music. Concert schedules are normally posted on the synagogue's door; otherwise, check the website for details.
