Mozart’s 50-room, dungeon-equipped ‘last castle’ can now be yours

At the foot of the Austrian ski town of Semmering, a historic castle that served as the final home of the late, great composer Wolfgang Amadeus Mozart will soon hit the auction block.

Built in 1130, the approximately 900-year-old abode has a total of 50 rooms spread over its palatial 26,909 square feet, which are set on 3.7 acres of land.

It underwent partial redesigns in the 15th and 17th centuries and has, over the years, hosted such famous visitors as Napoleon Bonaparte, Pope Pius VI, Princess Isabella von Bourbon-Parma and Emperor Franz Stephan von Lothringen, Top 10 Real Estate Deals reported.

It was previously listed for $13.127 million.

Named Schloss Stuppach, the landmark stunner “ is one of the few in Lower Austria still in private hands,” according to a listing by Sotheby’s International Realty, which will be accepting bids for the address beginning Dec. 1.

The four-story residence boasts a slate of amenities familiar to modern buyers, including a cinema, library and “extensive space for entertaining,” as well as uniquely old-school offerings, like a chapel and dungeon.

It, of course, also boasts being a significant part of music history: It was at Schloss Stuppach that Mozart completed his famous “Requiem” in 1792, which is today considered one of the most valuable manuscripts in the world.

Mozart died the year prior, in 1791, at age 35, leaving “Requiem,” his final masterpiece, unfinished.

Who and how the work was completed and delivered to the count who had commissioned it the following year is one of music’s great mysteries.

Previous owners of the castle have used it as a “world-class attraction and event center for music performances and lectures,” and it currently houses independent businesses including a castle shop, “club salon” and “experience theater,” according to the listing.
