Château, Class B cultural property château in Bad Zurzach, Switzerland.

Schloss Zurzach, formerly Villa Himmelrych or Villa Zuberbühler, is a factory owner's villa built at the end of the 19th century for Jakob Zuberbühler to plans by architect Hans Baumann of Villigen. It stands directly above the Rhine slope in a park. The building is in Historismus (Neo-Renaissance) style with Jugendstil elements, especially the windows. Its plan recalls a French château with a truncated steep roof and two asymmetrical corner towers.

The villa was built at the end of the 19th century for the shoe manufacturer Jakob Zuberbühler, to plans by the architect Hans Baumann of Villigen. After Zuberbühler's death it passed to his shoe factory Odermatt & Co. In 1978 Hugo Ammann bought it for the Antonie-Deusser-Stiftung, had it renovated and opened it as a museum for the painter August Deusser under the name Schloss Zurzach. It was placed under monument protection in 1986; after legal disputes it stood empty from 2009, and in 2019 the Park Himmelrych AG acquired it.

The building carries a name linked to the Zuberbühler family who once lived there and shaped its character. This connection to local heritage remains visible in the house's architectural details today.

The Schlosspark is open to the public free of charge every day of the year from 10 a.m. until dusk. The villa itself is not open to visitors, so the park is the part of the grounds you can enter. The site lies on the Rhine slope in Bad Zurzach.

The park around the villa occupies the site of the Roman military camp Zurzach, which lay on the road from Vindonissa to Arae Flaviae. The villa's west facade has a Jugendstil window rising through three storeys into the roof space, painted with coloured landscape and animal scenes; the cantonal conservation office counts its glazing among the finest Jugendstil ensembles in Aargau.
