Louis Zimmer donated the clock to the city of Lier in 1930 to commemorate the centenary of Belgian independence.

4

The automaton mechanism outside the tower showcases figures representing various social classes and historical figures from Lier's past.

Overview

The Zimmer Tower is a medieval gatehouse, originally known as the Cornelius Tower, transformed into an astronomical clock tower by clockmaker Louis Zimmer in 1930. The tower displays the 'Zimmer Clock,' a complex mechanism featuring 13 different clock faces linked to a single movement. It tracks astronomical cycles, including the phases of the moon, tides, and the zodiac, alongside standard time. The tower is situated in the center of Lier and incorporates remnants of the city's 14th-century defensive walls. Adjacent to the tower is the Zimmermuseum, which houses the original master clock mechanism and demonstrates its technical precision. The exterior automaton display reveals different figures reflecting historical eras at specific times. The tower underwent significant restorations in the early 21st century to preserve its intricate gear systems.

Insider tips

Walk around to the back of the tower to see the Zimmermuseum garden and gain a different perspective of the structure.

Check the automaton show schedule upon arrival, as the mechanical figures move at specific intervals throughout the day.

Visit the interior museum to see the gear mechanism in action, which is often more impressive than the exterior dials alone.

What to avoid

Do not mistake the exterior clock dials for the only attraction; many tourists skip the museum, missing the internal mechanical display.

Good to know

Closed on Mondays during the off-season; check local listings for potential winter closures.
