The Pepper pot
St Gummarus Tower, known as the “Peperbus” (Pepper pot) to the people of Lier, is 83m high.
Due to a number of catastrophes it took almost four centuries to build. We can see this from the various architectural styles: Gothic at the bottom, the octagon resting on this is late Gothic, the top octagon is late baroque and the tower roof is rococo. https://www.visitlier.be/en/see/points-interest/st-gummarus-tower
