Millesimovský palác, Celetná, Baroque palace in Old Town, Czech Republic

The Millesimovský Palace is a four-winged Baroque building at Celetná 597/13, with its main eight-axis facade facing Celetná and a plain seven-axis facade on Štupartská. The main portal has twisted pilasters and a volute-shaped shield, above which sits a cartouche with the Caretto coat of arms; the first floor carries rich Rococo stucco work.

Two or three Romanesque houses once stood on this site; their foundations were united into a single Gothic building, later adapted in Renaissance style. In the first half of the 18th century Count Kryštof Cavriani had it rebuilt in high Baroque form, probably by Anselmo Martin Lurago or František Ignác Prée. Jan Josef Caretto-Millesimo bought the nearly finished palace, completed the work in 1756 and placed his coat of arms above the entrance.

The palace bears the name of Jan Josef Caretto-Millesimo, who bought the nearly finished building and completed its reconstruction in 1756, placing his coat of arms above the entrance. In the 19th century it housed a noble casino and a luxury restaurant; since 1990 Charles University has used its rooms.

The palace is near several tram lines and located in the heart of the Old Town tourist area. It is easy to visit on foot while exploring other historic sites nearby.

In the cellar beneath the west wing, the ground plan of a former Romanesque house survives, and the roof's brick gable walls are probably late Gothic. A broken Gothic portal also remains in the ground floor of the Štupartská Street facade.
