Losyovský Palác, Baroque palace in New Town, Prague, Czech Republic

Losyovský Palace, known today as the People's House (Lidový dům), is an early Baroque palace at Hybernská 1033/7 in Prague's New Town. Carlo Lurago built it in 1651–1657 as a four-wing, two-storey building around a courtyard; the Hybernská facade has 24 axes, and the early Baroque entrance portal survives beside the right risalit. The rear wing keeps blind arcades with stucco work.

Carlo Lurago built the early Baroque palace in 1651–1657 for Count Jan Antonín Losy of Losinthalu on the site of three older houses. A fire and Prussian artillery damaged it in 1757, and Jan Křtitel Plonner had Filip Heger rebuild it in Neoclassical style in 1787. The Kinský family owned it from 1799 to 1879, and in 1907 the Social Democratic printing and building cooperative bought it and renamed it Lidový dům.

The name Lidový dům (People's House) dates from 1907, when the Social Democratic Printing and Building Cooperative bought the palace. In January 1912 the VI All-Russian Conference of the Russian Social Democratic Labour Party was held here under Lenin's direction. A plaque in the courtyard, unveiled in 2009, recalls the 1968 attempt to renew the Czechoslovak Social Democracy.

The palace stands at Hybernská 1033/7 in New Town, Prague 1, a short walk from Masarykovo nádraží and the Hybernia theatre. It is the seat of the Social Democratic Party, so the courtyard and historic interiors are not a regular public sight; the early Baroque entrance portal beside the right risalit can be seen from the street.

During the 1951–1952 conversion into the Lenin Museum, painted 17th-century ceilings were uncovered and restored. The rear wing, once a connecting gallery, retains blind arcades with stucco decoration from Carlo Lurago's Baroque phase after 1651.
