Peleș Castle is a Neo-Renaissance castle in the Carpathian Mountains, near Sinaia, in Prahova County, Romania, on an existing medieval route linking Transylvania and Wallachia, built between 1873 and 1914. Its inauguration was held in 1883. King Carol I (Charles I) of Romania (1839–1914), under whose reign the country gained its independence, first visited the site of the future castle in 1866 and fell in love with the magnificent mountain scenery. The estate was named the Royal Estate of Sinaia. The monarchy commissioned the construction of a royal hunting preserve and summer retreat on the property, and the foundation was laid for Peleș Castle on 22 August 1873. Peleș Castle became the world's first castle fully powered by locally produced electricity. In more recent times, many foreign dignitaries such as Richard Nixon, Gerald Ford, Muammar al-Gaddafi, and Yasser Arafat were welcomed at the Castle.
The castle was featured in the 2009 film The Brothers Bloom. The exterior of the castle is used to represent a large estate in New Jersey, the home of a eccentric billionaire played by Rachel Weisz.
