Коловратский дворец, Baroque palace in Malá Strana, Prague, Czech Republic

The Kolowrat Palace is a Baroque corner building at the junction of Sněmovní and Thunovská streets in Malá Strana, Prague. Its main facade on Sněmovní street has an aedicula portal, and the side facade on Thunovská street has an oriel window. The interior decoration dates from 1992, when the building was adapted for the Chamber of Deputies; only the ceiling frescoes survive from the Baroque rebuilding around 1690.

The site began as a Gothic house, rebuilt several times; its first known owner, in 1466, was carpenter Jan Sekyra, and it was later called Bělehrad. After 1626 it served as the parish house of the Malá Strana church of St Wenceslas, and when that church vanished in 1772 the name changed to the parish house of St Nicholas. Around 1690 it was rebuilt in Baroque form, with alterations by Giovanni Antonio Lurago in 1707 and layout changes in 1884.

The building is owned by the Prague Archdiocese and used by the Chamber of Deputies as the seat of its Parliamentary Institute. Its name recalls the Kolowrat family, who gave the house its name in the early 17th century; after 1626 it served as the parish house of St Wenceslas, then of St Nicholas. The baroque ceiling frescoes from around 1690 survive above interiors remodelled in 1992.

The building stands at the corner of Thunovská and Sněmovní streets in Malá Strana, near the lower house of Parliament. It is owned by the Prague Archbishopric and used by the Chamber of Deputies as the seat of its Parliamentary Institute, so access is tied to that institutional use rather than to regular sightseeing.

The baroque ceiling frescoes inside date from the rebuilding around 1690 and survived the 1992 conversion for the Chamber of Deputies; all other interior decoration is modern. The building belongs to the Prague Archdiocese and houses the Chamber's Parliamentary Institute.
