The frescoes of Branko Sotra, a painter from Stolac, who resided illegally at Donji Dubac, were painted in 1942. in the house "zidanica" of Spasoje Tadic. In the absence of paints he used yolk, soot and milk. On the walls of two rooms a small set of wall paintings is presented, describing: a mother and a child, a young man with a basket of apples, an old man sharpening a scythe, a carpenter, a waist high picture of a boy and a girl, outdoor party, at dinner, a note: sum­mer of 1942. Branches and grapevine at the edges of each painting are compulsory ad­dition to the composition of paintings. This unique, law protected work of art, is treated as invaluable proprety of Dragacevo.

In 1981, the house of Tadic, treasuring these picturesque frescoes, was declared cultural property.
