The oldest part of town is along the river, as evidenced by the ramparts of the old fort, which dates from 1410. The hill is topped by the simple 1699 Assumption Cathedral (Успенский собор), one of Levitan’s favourite painting subjects. From the cathedral the road winds down to the main square. The town’s oldest street is supershort ul Kalashnaya . It has been converted into a flea market and descends to the embankment.
