Pálffy Palace is a Baroque-style palace in the Old Town of Bratislava, on Ventúrska street. It was built by Count Leopold Pálffy in 1747. It has an interesting portal with a relief reflecting the military career of the count as a general in the army of Empress Maria Theresa. During the reconstruction of the palace, parts of a Gothic building were found in walls at the interior of the building. Roman and Celtic finds were uncovered through archaeological research in the basement. The palace used to contain a mint in the past. Some believe that in 1762, the six-year-old Wolfgang Amadeus Mozart played a concert at the Palace, though there is dispute amongst historians on this point. From 1993 to 2012, the palace was used as the Austrian embassy.
