Käfigturm (Prison Tower), Bern (must see)

The Prison Tower is one of Bern’s most recognizable historic landmarks and a reminder of the city’s former defensive walls. Standing in the middle of Market Street, only a short walk from Federal Square, it once served both as a city gate and as a prison. The first tower was built in 1256 as part of Bern’s second line of fortifications, created after the city expanded westward. By the 17th century, however, the original structure had fallen into poor condition and was demolished.

The present tower was constructed in 1640. Designed to hold approximately 60 to 70 prisoners, it remained in use as a jail until the late 19th century. Common criminals, debtors, and other detainees were once confined in its cells, giving the building its English name.

After the prison closed, the tower took on several different functions. At various times, it was used to store state archives and court records, and it later housed a wine shop, a library, and an exhibition center. Today, it is associated with public exhibitions and events, particularly those dealing with politics, democracy, and civic life.

Approaching along Market Street, visitors can easily identify the tower by its massive arched gateway, tall sandstone walls, decorative upper section, and prominent clock. The bell above the arch dates from 1643 and was cast in eastern France. Its inscription asks that its voice terrify evil spirits. Originally struck by hand, it later received a mechanical striking system during the 19th century and still rings when the clock mechanism is properly wound.

Visitors can walk or ride a streetcar directly through the gateway, just as travelers once passed through the medieval city entrance. Although many tours focus mainly on the exterior, the building can sometimes be entered for exhibitions.
