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.

Construction of this palace began in 1713 under architect František Maxmilián Kaňka, who shaped it into its current Baroque form. The site had earlier hosted a Gothic house that underwent Renaissance modifications before the Baroque redesign.

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.
