Blois, France - This majestic 17th-century château was the home of the Marquise de Pompadour, King Louis XV's favorite. Set in a 104-acre park, perched high on the banks of the River Loire, this property comprises the chateau and various beautiful period outbuildings with reception rooms, guest rooms, a 30,000-bottle wine cellar and an orangery. The chateau, flanked by symmetrical wings and pavilions, offers breathtaking views of the Loire River and boasts a vast gallery, 34 bedrooms and 24 bathrooms, a superb staircase, parquet floors and multiple chimneys. Pompadour enlisted court architect Ange-Jacques Gabriel - who designed Paris's Place de la Concorde - to build her dream home, refurbishing the original château, which had been built in 1642. All surrounded by a magnificent park, rotunda, nymphaeum, basin. The property boasts a long avenue of century-old linden trees, stretching two miles, and over a mile of frontage on the River Loire. The lavish geometric gardens were designed by landscape architect Le Nôtre, the principal gardener of King Louis XIV, who also designed the gardens of the Palace of Versailles. The Château de Menars, situated 116 miles south of Paris in the heart of the Loire Valley, a UNESCO World Heritage site, offers a huge potential for further development. Price: €15,750,000.
