Taken by the enchanting Bucegi Mountains, King Carol I commissioned the construction of a neo-Renaissance-style castle in the quaint village of Sinaia during the 1860s. The royal summer house contains 160 rooms, all of which have a distinctive theme. For example, the theater on the grounds asserts a storybook feel with exquisite frescoes by Austrian artists Gustav Klimt and Franz von Matsch climbing the walls and ceiling.
After years of serving as a royal residence, Peleș Castle was eventually abandoned when Romania fell under Communist rule. The castle reopened as a public museum after the revolution in 1989.
