Zunfthaus zum Rüden, Medieval guild house at Limmatquai, Zürich, Switzerland

Zunfthaus zum Rüden is a free-standing building on Limmatquai whose upper timber-framed storey overhangs stone walls about one metre thick. Its Gothic hall, the former Trinkstube, has an eleven-metre-wide curved wooden ceiling with carved beam ends, and now serves as a restaurant hall.

The city council ordered the original timber building to be rebuilt in stone in 1348. This transformation made it the new seat of municipal authority and a symbol of Zurich's growing power.

The Constaffel society, founded in 1336, gathers in this building to maintain medieval craft traditions that shaped Zurich's identity. These guild customs remain visible through the formal halls and their continued use for civic assemblies.

The building stands free of its neighbours on Limmatquai, projecting slightly toward the Limmat opposite the Münsterhof and the Zunfthaus zur Meisen. A pedestrian walkway runs under its arches along the water, added at the city's request so the house matched the surrounding guild houses. The upper timber-framed floor overhangs the roughly one-metre-thick stone walls on both long sides.

The house name first appears in 1358 in a Fraumünster rent register, and from 1401 the "Trinkstube der Herren zum Rüden" is documented. The hound in the Constaffel coat of arms stood for the aristocratic hunting right of the society's noble members.
