The Water Tower of the Chapel Bridge
The Water Tower in Lucerne was built around 1300 as a watchtower. At that time, Lucerne was under Habsburg rule. The wooden Chapel Bridge followed a few decades later in 1365.
The tower is octagonal. It is 34.5 metres (113 feet) high, has a circumference of 38 metres (125 feet), and the walls are up to 4 metres (13 feet) thick.
Top Floor — Former Torture Chamber

Luzerner Schilling 1513, Folio 129v, S.262
Today, the
top floor beneath the roof is used by the
Ornithological Society for bird observation.
In the
Middle Ages, this room was used for
torture during “embarrassing interrogations.”
During the
French occupation (1798–1804) it also served as a
military prison for deserters.
Second Floor — Salon
On the
second floor, there is the
salon of the Artillery Association.
In earlier centuries, this room housed the
treasury chamber of the Republic of Lucerne.
The Secret Chamber
Between the
second and first floor there is a
secret chamber, constructed
after
the theft of the state treasury. When it was rediscovered around
1900, the chamber was
found empty.
First Floor — Weapon Collection
The Dungeon
In the middle of the room there is a shaft leading 6 metres (20 feet) down to the dungeon.
The
large stone lid was used to close the opening. Prisoners were
lowered into the dungeon by rope, after which the lid was closed, leaving them in darkness. Food was passed through a
small hole in the lid.
The conditions of imprisonment in the dungeon were extremely harsh. Therefore, it was mainly used as a temporary interrogation prison.
Long-term prisoners were kept elsewhere — in one of the
30 towers that Lucerne possessed during the Middle Ages.
