Salzhaus, Concert hall in Winterthur, Switzerland.

Salzhaus is a concert venue housed in the former salt, grain and goods warehouse of Winterthur's old freight station, a long neoclassical-Renaissance building with a pitched roof erected in 1861–63. Up to 600 people fit in during concerts, and Swiss Post premises share the same building.

The building was erected in 1861–63 as the salt, grain and goods warehouse of Winterthur's old freight station, designed by city architect Karl Wilhelm Bareiss after plans by state building inspector Johann Caspar Wolff. Its construction was part of an agreement between the city and the Nordostbahn railway to build a freight yard south of the main station. The concert venue opened in October 1996, founded by a group of seven friends who had spotted a newspaper advertisement for the premises, previously rented as a paint company's storeroom.

The name comes from the building's former role as the city's salt, grain and goods warehouse at the old freight station. In its first years the club also hosted acid-jazz and funk parties alongside concerts. Since 2004 it has belonged to a association with Gaswerk, Kraftfeld and Albani that distributes the city's subsidy funds.

The venue sits in the former goods station building south of Winterthur's main station, in the Stadt district; the Post office occupies other parts of the same building, so look for the Salzhaus entrance. Concerts fit up to 600 people. The building is a listed communal monument, and the club has been run as a GmbH since its early years.

The building is a former salt, grain and goods warehouse of the old freight station, built 1861–63 by city architect Karl Wilhelm Bareiss to plans by Johann Caspar Wolff. It is a long neo-Renaissance structure with a gabled roof, under municipal heritage protection, and Swiss Post premises still occupy part of it.
