Social Museum of the Sanok Land came into being in 1934. Then, in 1960 it changed its name into Historical Museum in Sanok. The new Zdzisław Beksiński Gallery was open in 2012 in the rebuilt part of that museum. Thousands of Beksiński's works have been collected there. It means drawings, graphics, art photographs, reliefs, sculptures, pictures and computer photo montages. They testify all seasons of his creation. We can also see there: records, films, notes and documents connected with his life.
The guests staying in Sosnowa Aleja were very surprised when they saw the variety and a large number of exhibits in Historical Museum in Sanok. In that museum you can also see the collections of:
