Peles Castle - The castle in Peles Valley, the summer residence of Romanian royalty, was built during the rule of Carol I (1866-1914) and today it is an important national monument of XIX century Europe. Several other buildings,annexed to the castle, were built simultaneously: Pelisor Castle, The Guard's Chambers, The Economat, The Foisor Hunting House, The Stables, the Electrical Power Plant and the "Sipot" Villa. Until the completion of Peles Castle(1883), the royal couple lived in the hunting house. Due to the electrical plant in the Peles Valley, Peles Castle was the first European castle entirely lit by electrical current.
