The Gallery of Ancient Bulgarian Art presents an exceptional collection of religious art (mostly icons) dating from the 12C to the 19C. The most interesting items include: a 12C St Nicholas, the altar doors of Boboševo Monastery (1488) and an outstanding carved iconostasis originally in the church of the Intercession of Rila Monastery (19C). Not to be missed: the mural paintings of the church of St-George in Nesebur and the evolution of icon painters discovered during the period of the National Awakening.
