Faust House, Gothic and Renaissance palace at Charles Square, Czech Republic

Faust House is a two-storey, four-winged palace with an inner courtyard on the south side of Charles Square in Prague's New Town. Its twelve-axis facade is pale pink with white pilasters, a stepped gable with an oculus, and the inscription "FAUSTINUV DUM" above the arched entrance. A polygonal oriel sits on the western corner.

A house is first recorded here in 1378, held by Duke Jan of Opava; the Gothic core was rebuilt in Renaissance style around 1618. Baroque remodelling came in 1725–1740 under F. M. Kaňka and again in 1769 by Antonín Schmidt, who added a courtyard wing.

The palace took its name from former residents like Edward Kelley, who conducted alchemical experiments that sparked local legends about Doctor Faust. These stories have shaped how people think about the building ever since.

The building is owned by the City of Prague and used partly by the First Faculty of Medicine of Charles University and partly by the General University Hospital. A passage through the vestibule and courtyard links Charles Square to the hospital complex. The western wing faces a narrow garden above the Church of Saint John on the Rock.

The Faust legend holds that the devil tore a hole in the ceiling when he carried Dr. Faust away, and that masons could not close it for a long time. The story was spread by writers such as Alois Jirásek and Jan Kollár, and the house's alchemical owners kept it alive.
