Raekoja plats, the cobbled market square at the heart of the Old Town, is as old as the city itself. On its southern side stands the fifteenth-century Town Hall (Raekoda), boasting elegant Gothic arches at ground level, and a delicate steeple at its northern end. Near the summit of the steeple, Vana Toomas, a sixteenth-century weather vane depicting a medieval town guard, is Tallinn’s city emblem. The well-labelled and informative museum inside the cellar hall (late June to Aug Mon-Sat 10am-4pm; rest of the year closed; €5) depicts Tallinn town life through the ages. For an expansive view of the town square, climb the spiral staircase of the Town Hall Tower (Raekoja Torn; May- to mid-Sept daily 11am-6pm; €3).
