Sonnenhof, Historic building in Bolzano, Italy

Sonnenhof is a four-storey historicist building at the corner of Fagenstraße and Egger-Lienz-Straße in Bozen's Gries-Quirein district, built in 1887/88 to a design by Josef Adam Irschara. It is the last largely unchanged hotel building of the former spa town of Gries, with its original facade and window arrangement intact. North of it stands the Italian-language primary school Antonio Rosmini, added in the 1960s, which shares the courtyard with the student hostel.

The Sonnenhof was built in 1887/88 as a hotel and sanatorium in the historicist style, designed by Josef Adam Irschara on the initiative of Minna Ottilie Scholvien-Wendlandt. It was first run by Conrad Gilbert, director of the Tarasp spa house, with Therese Archauer as first innkeeper. Renamed Hotel Regina, it was expropriated in the late 1920s and from 1931/32 housed the Convitto nazionale Damiano Chiesa, opened on 30 April 1932 by Duke Emanuele Filiberto of Savoy. In 1943–45 the Wehrmacht used it as a military hospital; from 1946 it again served as a boarding school, and in 2001 it passed to the Province of South Tyrol.

The name Sonnenhof ("sun court") comes from the hotel era; the street on the east side, Egger-Lienz-Straße, was formerly called Wendlandtstraße after Minna Ottilie Scholvien-Wendlandt, who initiated the building. In January 1896 a commemorative ceremony for the 25th anniversary of the German Empire's founding in 1871 was held in its rooms. Since 1931/32 it has served as the Convitto nazionale Damiano Chiesa, a boarding school for about 70 upper-school pupils.

The Sonnenhof stands at the corner of Fagenstraße and Egger-Lienz-Straße in Gries-Quirein, diagonally opposite the Weinhof Schmid-Oberrautner. Its east side and schoolyard border the Herzogpark, which holds tennis courts, a children's playground and the government commissioner's office. The building itself is a boarding school and not open to visitors; the surrounding streets and the park are reached on foot.

The Sonnenhof is the last hotel building of the former spa town of Gries to survive largely unchanged structurally. Its annex Sonnenheim still stands as a converted house on Egger-Lienz-Straße, while the neighbouring Wilhelma and Loreley buildings, the latter housing a public bathing establishment, were demolished or rebuilt in the 1930s.
