The Icon Museum of Trjavna's school is housed in the former chapel of the sanatorium. Two rooms present the production of the local school of icon painters, whose graceful style borders on mannerism. The room on the right displays 18C and early-19C icons, including a superb Christ Pantocrator, and works by Jonko Pop Vitanov. The second room exhibits a triptych depicting St George by Simeon Simeonov, as well as an Adam and Eve. Also displayed are the instruments used by painters of icons.
