The impressive 17th-century synagogue in Lesko was built in the mannerist-baroque style. The building resembling a castle was the main synagogue of the Lesko Jewish community. On its facade you can see the relief of the Mosaic Tablets and the Hebrew inscription: "Oh, what a fear this place fills! Nothing here but God's House! " The peak line decorated with vases is also noteworthy - the only solution of this type in the synagogue in Poland. It is worth taking a look inside, because today the synagogue houses the Art Gallery of the Bieszczady Culture House and the Museum of the Jews of Galicia.
Once the synagogue was part of the city's fortifications. It also housed a prison. Until World War II, Jews constituted a significant part of the local community, and in Lesko there were several prayer houses. After the war, the devastated synagogue was going into decline, and it wasn't until the 1960s that local authorities subjected it to renovation.
One of the oldest European cemeteries is located near the synagogue.
