Grote Markt, town hall and belfry

The Lier Grote Markt is triangular, perhaps of Frankish origin, and almost all its houses were destroyed in 1914; the town hall and the belfry of 1369 came through almost intact. The belfry has been a World Heritage Site since 1999 and its little carillon plays a tune every quarter of an hour. Beside it you will see a brass band in the ground: the meridian line of Adolphe Quetelet, who used a corner of the town hall as a gnomon. Among the cobbles there is also a witches' stone, a reminder of the women burned here.

In the town hall, with its spiral staircase, the tourist office is on the first floor. The square is closed to cars from 11:00 to 18:00.
