Situated in the beautiful Prahova Valley at the foot of the Bucegi Mountains, Sinaia is regarded as the Pearl of the Carpathians. About an hour north of Bucharest, Sinaia is home to the fabulous Peles Castle, a fairy-tale-like ediface built by King Carol 1 in the 19th century as the royal family's summer residence. Its interiors are an opulant display of elegant design and historical artifact. Other tourist landmarks include: Pelisor Castle, Sinaia Monastery, Sinaia Casino, Sinaia train station, and the Franz Joseph and Saint Anne Cliffs. Sinaia was also the summer residence of the great Romanian composer George Enescu, who stayed at the Luminis villa. Sinaia is also a popular destination for hiking and winter sports, especially downhill skiing.
