The tour begins at the square on Rathausquai, beside the wooden Chapel Bridge on the right bank of the Reuss. A blast of the fire horn signals the start, and Nightwatchman Ralf introduces himself and his life during the Middle Ages using the Martiniplan, a 400-year-old copper-engraved city map.

Switzerland's most photographed landmark conceals remarkable history within its medieval walls. The Water Tower predates the wooden bridge by several decades and held a torture chamber among other dark secrets, all recounted in detail by the guide.

Moving through the ghost-haunted Furrengasse and into Kornmarkt, once the city's central grain market, the group reaches the early 17th-century Town Hall with its tower and the former bakers' guild house, the Pfistern. Historical measurement markers and the tale of the Giant of Reiden add texture to this stretch of the route.

The Alley of Fire leads into the story of the Riot of Lucerne and the city's medieval bid for independence. At the Wine Market, the city's oldest stone fountain stands before beautifully painted house facades, while the Lower Wine Market once served as an open-air court with a pillory at its center.

The Nightwatchman explains the mechanics of medieval justice at this key location: prosecution methods, interrogation techniques, forms of corporal punishment, and the administration of the death penalty. The account draws on documented historical practice rather than legend.

Crossing the Reuss Bridge, the group passes the house of the Swiss King, the former pawn shop and mint house, and the window of the medieval Alte Suidtersche Apotheke pharmacy. Back at Rosengart Platz, the Dance of Death paintings are projected before the group as the Nightwatchman narrates their haunting meaning.
