Palác Pachtů z Rájova, Baroque palace in Old Town, Czech Republic

The Palác Pachtů z Rájova is a four-wing baroque building with an almost square plan around a courtyard, its main Celetná facade of 14 window axes centred on a portal bearing stucco medallions of Maria Theresa and Francis Stephen of Lorraine. The side facade on Králodvorská has 9 axes.

Four medieval houses on the site were merged in the 15th century and rebuilt in Renaissance style; after the French fire of 1689 they were joined into one house. In 1737 Knight Josef Ignác von Langer bought it and had Kilian Ignaz Dientzenhofer design a high-Baroque reconstruction, finished in 1740. The Pacht family owned it from 1801 to 1822, and after 1840 Jan Ripota added Classicist changes.

The palace carries several names: Pachtovský palác after the Pacht family of Rájov, who owned it from 1801 to 1822, and Seebergovský palác or Langerovský dům after earlier owners. The stucco medallions of Maria Theresa and Francis Stephen of Lorraine above the Celetná portal recall the Habsburg era.

The palace stands at Celetná 585/31, with a side facade on Králodvorská 585/2 in Prague's Old Town. It now serves as an administrative building for the Ministry of the Interior, so interiors are not open to tourists. From the street you can see the 14-axis main facade and the portal with stucco medallions of Maria Theresa and Francis Stephen of Lorraine.

The palace's courtyard wings were raised by one storey and given arcaded galleries after 1840 by builder Jan Ripota, and the courtyard itself was roofed over in the 1930s when a bank occupied the building. A Baroque ceiling from Dientzenhofer's rebuilding survives in a first-floor room.
