This mansion, dubbed Palais Montmorency, is located on Paris’ famed Avenue Foch and comes with a whopping €100,000,000 ( $136,000,000 ) price tag, which makes it the 2nd most expensive residential proprety for sale in the world right after Candy Speling’s $150 million behemoth. It was built in 1912 for the Duchess of Montmorency. After her death in 1927 the house was acquired by famous art collector Antenor Patino. It boasts 31,000 square feet of living space with 12 bedrooms, 12 bathrooms and 4 staff/guest apartments.
