Wieluń is an overlooked town in central Poland that’s worth a visit for its well-preserved medieval centre. The main square is a beauty, surrounded by half-timbered houses and dominated by a Gothic town hall. There are also some lovely churches, including the towering St. Mary’s Basilica. The old town is small enough to explore on foot, and there are a few decent restaurants and pubs if you need a break from sightseeing. You can also visit the remains of Wieluń Castle, which was destroyed during World War II.
