Trnava retains more of its medieval fortifications than almost any other city in Slovakia — a substantial length of the 14th-century walls survives, along with several towers and a partially restored moat area. The walls form a roughly oval circuit around the old town and are walkable in sections, offering views both inward across the church towers and outward toward the surrounding plain.
Several towers have been preserved or restored, including the Michael Tower at the northern approach. The best-preserved stretch runs along the western and southern sides of the old town. Walking the walls is free and takes about 30 minutes for the accessible sections; it gives a good sense of the city's medieval extent and the confidence its founders had in their defenses.
