In Donji Dubac on the Orlujak hill, in the house of Spasoje, now of Tihomir Tadic, there is unique gallery of frescoes, whose author is Branko Sotra, academic painter. During his stay in Donji Dubac, from the beginning of November 1943 to the end of January 1943, where he was hiding as a member of  Kopanik partisan squad, with not so rich artistic material (eggs, milk, soot), he decorated the house walls with the frescoes. On them we can find motives from village life.

Frescoes were restaurated in 1975 and the house is under the protection as a cultural monument because the frescoes have great artistic value and historical importance.
