Three-aisled cathedral with a 100-meter tower was built in the late Gothic style. This huge temple is famous for long-term construction. From the laying of the foundation in 1421 until the end of the vaults aisles it has been more than a half century. The top of the tower was rebuilt in 1893.

Of particular interest is the main portal (1490-1500 gg.) Cathedral. Impressive bas-reliefs depicting the Last Judgment. The rich interior of the Cathedral stained glass windows stand out luxury.
Near the cathedral is an observation deck, which offers a beautiful view of the streets of the city, the river Aare and the mountains.
