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.

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


Salon of the Watertower


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


Opening to 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.

Mount Pilatus strongly stimulated the imagination of the people in Switzerland early on. This was because it seemingly rose gently from the flatlands, but then suddenly jutted steeply upwards in massive rock formations. The ancients called it "Fractus mons" (broken mountain) or Frakmont . They considered it nothing more than a split and broken-up mighty hill. Since the people of antiquity could not explain the elemental forces that once split the mountain, they saw in them the work of evil powers. Because fire, water, storms, and lightning had always terrified the residents, they believed that these forces were causing mischief on the mountain. In the ignorance of the Middle Ages, one thing was clear: spirits lived there. In the stories, one heard of dragons, ghosts, spirits, hobgoblins (Herdmännlein), and mischievous dwarves (Toggelis); even the Türst and the Sträggele caused trouble there.

Lucerne, 1758. The Golden Time of the Republic was coming to its autumn. Wars and bad harvests in Europe meant that the soldier contracts, which the city lived from, were paid slowly. This made the state treasury, the heart of the Lucerne Republic, even more important.  It was stored in the safest place you could think of: in the upper room of the Water Tower. The Reuss river flowed around it, and you could only reach it over the Chapel Bridge or by boat.

A painting on the Chapel Bridge (panel Nr. 25) once showed a famous Lucerne legend: The Emperor Charlemagne giving special "Harsthörner" (war horns) to warriors from Lucerne to honor them. (Please note: This original painting was unfortunately destroyed in the 1993 Chapel Bridge fire and is no longer on the bridge.) The legend says that in 778, warriors from Lucerne joined Charlemagne’s army in Spain. They bravely saved his nephew, Roland, in a battle. As a "thank you" for their loyalty and courage, the emperor gave them the special war horns, a great privilege.

Just like any good craftsman, the executioner tried to do a "clean" job. When it came to torture, he was only allowed to go as far as it was useful—he wasn't supposed to kill them. The executioner had to be extremely careful that the tortured prisoners didn't die, so they could still be brought to their "real" punishment.

In the beginning, as serfs of the Hofkloster (monastery), we got our judgement at the Marienbrunnen (Mary's fountain) by the stairs of today's Hofkirche. From the middle of the 13th century, the Habsburgs allowed us to hold court ourselves . This happened at the lower fish market (unterer Fischmarkt), by the court linden tree. Later, the first town hall of Lucerne (the building before today's Hotel Des Balances) became the court place. The executions happened at the Sentimatt execution place .
detail: the  wild hunt, Peter Nicolo
By Ralf Fioretti October 25, 2025
On the heights of Mount Pilatus, a ghostly figure roams—a creature that is part "wild man," part "spirit," part "warrior," and part "god." This being, called Türst , causes great trouble for the alpine herdsmen and torments their cattle in many ways. His power is strongest when the herdsmen stray from a godly life. He is a fearsome hunter from the underworld. At nightfall, Türst prepares for the hunt. He drives the poor cattle before him, scaring and confusing them so much that they run wildly in all directions. Sometimes, they even leap down into the valley, forcing the herdsmen to struggle to bring them back up. The cows remain without milk for a long time after such encounters. When Türst approaches, he blows a powerful hunting horn. Every animal that hears it must come and stand before him. He is often accompanied by a pack of hellish dogs , all of which have only three legs . Leading the pack is a massive dog with a single eye in the middle of its forehead . This dog jumps ahead, with the entire pack stumbling behind it, constantly falling over due to their missing legs. In the middle of it all is Türst , part hunter, part spirit, part ghost, and part warrior.

The purest and best-tasting water in Lucerne can be found in the fountains of the historic old town. Unlike the houses and hotels, which receive their water through pressure pipes, these fountains have their own independent water supply, dating back to the Middle Ages.
