The old town centre of Grabovo is worth a visit. Reached via Aprilov bridge, it includes the main square on which stands the church of Our Lady, 1-May square, dominated by a tower pierced with loopholes and 10-July square. The latter leads to a fine group of houses in the National Awakening style. One of these houses the Museum of Urban Life. Nearby stands the church of the Holy Trinity (Sv. Troica), which has retained an attractive, elaborately carved iconostasis.
