New Royal Palace, Royal residence in Prague Castle, Czech Republic

The New Royal Palace is the complex of wings on the western side of Prague Castle, built from the 16th century and unified behind a single late-Baroque facade by Nicolò Pacassi between 1753 and 1775. Its entrance wing frames the First Courtyard, where the Matthias Gate of 1614, the oldest surviving secular Baroque structure in Bohemia, leads through to the Second Courtyard.

The palace was assembled between 1564 and 1616 from older buildings under Bonifaz Wohlmut, Giovanni Gargioli and Giovanni Maria Filippi, starting under Maximilian II and finished under Matthias. Maria Theresa had Niccolò Pacassi rebuild it in 1753–1775, giving the wings around the second courtyard a uniform late-Baroque facade. After 1918 Jože Plečnik adapted interiors for President Masaryk.

The palace has housed the head of state since the last third of the 16th century: the king, then the president, and during the German occupation the Reichsprotektor. The Vladislav Hall in the adjacent Old Royal Palace served coronations, while the New Royal Palace holds the offices and reception rooms of the President of the Republic.

Most of the palace is closed to the public and used by the Office of the President; only the exhibition halls on part of the ground floor are open. Enter from Hradčanské náměstí through the Matthias Gate into the first courtyard, or from the Royal Garden over the Powder Bridge to the second courtyard. The Prague Castle Picture Gallery and the Imperial Stables occupy the former stables of the north wing.

Under the palace, archaeologists uncovered in 1950 the remains of the Virgin Mary Church, the castle's oldest church. Its nave, chancel and altar table survive, with masonry from the 9th century below and 11th-century work above; the ground floor was adapted in 1964 so visitors can see them.
