Clam Gallas Palace

The Clam-Gallas Palace is one of the finest Baroque palaces in Prague, built in 1713–30 for Count Jan Václav Gallas to a design by Johann Bernhard Fischer von Erlach — the leading Baroque architect of the Habsburg world, also responsible for the Karlskirche in Vienna. The entrance portal on Husova Street is flanked by two colossal Hercules figures by Matthias Bernard Braun, one of the most striking Baroque doorways in Central Europe. The ceremonial interiors on the piano nobile feature ceiling and wall frescoes by the Italian painter Carlo Carlone depicting mythological themes. Over the centuries the palace hosted concerts by Mozart and Beethoven and served variously as a military headquarters and post office. Today the City of Prague owns the building, which houses the Prague City Archives. Its 99 rooms underwent extensive renovation in 2018–22, restoring the façade, courtyard, and interiors. One of the most architecturally significant and least-crowded Baroque interiors accessible to visitors in the Old Town.
