Oettingenský palác, Baroque palace in Malá Strana, Prague 1, Czech Republic

Oettingenský palác is a Baroque palace at the corner of Letenská 23 and Josefská 6 in Malá Strana, Prague. Its asymmetrical west facade in Josefská Street has banded rustication on the ground floor, a Baroque portal, Ionic pilasters on the upper floors, and a shallow two-axis central risalit with a triangular pediment flanked by two dormers. A rare prampouch arch with a corridor once linked the first floor to the empora of St Thomas Church.

The first documented building on the site dates from 1406; a Gothic house there was destroyed in the Hussite wars, and in 1456 the community granted the plot for new construction, which for a time housed a slaughterhouse. In 1548 Marshal Ladislav of Lobkowicz acquired it, and his family built a Renaissance palace on the medieval foundations. After a fire in 1723 the Lobkowicz builder Antonín Ritžich rebuilt it in High Baroque style to a design by František Maxmilián Kaňka; in 1841 Prince Bedřich Oettingen-Wallerstein bought it and gave the palace its name.

The palace's name comes from Prince Friedrich of Oettingen-Wallerstein, who bought it in 1841; second-Rococo tiled stoves from that period survive inside. A prampouch passage with a corridor once linked the palace's first floor to the empora of St Thomas Church, used by the Lobkowicz and Oettingen-Wallerstein families to attend services.

The palace stands at the corner of Letenská 23 and Josefská 6, next to the Church of St Thomas on its north side. A pedestrian passage was cut through the building beside the Letenská entrance in 1927 and converted for vehicle traffic in 1948, when the former carriage entrance became a new passageway.

The palace preserves a rare layering of architectural periods, with Renaissance and Baroque elements visible on the ground floor in ways rarely seen together in Prague. This stratification lets visitors trace several centuries of building history in a single location.
