Ehemalige Kammgarnspinnerei, Industrial heritage site in Schaffhausen, Switzerland

The Ehemalige Kammgarnspinnerei consists of two connected factory wings. The Baumgartenstrasse wing is a four-storey industrial building of light-coloured brick with segmental-arched windows and a further attic storey with large south-facing windows. The adjoining west wing on Klosterstrasse, built in 1912, is a five-storey reinforced-concrete skeleton structure, one of Switzerland's earliest.

The mill was built in the 19th century when Schaffhausen became a major textile production center. As the regional textile industry declined later, the building was repurposed and eventually protected as a heritage site.

The name Kammgarn refers to combed wool yarn; the Chessex, Hoessly, Lang & Weidlich mill opened here in 1867, and the Chessex & Hoessly spinning works later became known under the brand "Schaffhauser Wolle". Since 1997 the Kulturzentrum Kammgarn has occupied the building, with the KiK action hall, the Vebikus gallery and the TapTab music club. The FATart art fair has shown contemporary art by women artists there since 2016.

The site is walkable from the town center and located in a traditional industrial quarter. Visitors should wear appropriate layers, as the interior spaces can feel cool regardless of the season.

The west wing, built in 1912, was one of Switzerland's first reinforced concrete structures. From 5 May 1984 it housed the Hallen für Neue Kunst, where Carl Andre's 18-tonne Cuts and Joseph Beuys's two-storey room sculpture Das Kapital Raum 1970–1977 were shown. The collection closed and moved after legal disputes in 2014.
