The past of the Peleș Palace is closely connected to the history of the Romanian Royal Family. The palace was built close to the monastery of Sinaia by King Carol I of Hohenzolern-Siegmaringen and his wife, Queen Elizabeth (1843-1916), in 1873. Until 1947, the castle was the secondary residence of the royal family. It often received in its salons many artists and writers, including Elena Văcărescu (1864-1947), the French writer of Romanian origin. 

Made into a museum in 1953 and later closed to the public for many years during the communist regime, the castle is now open to the public. The exterior architecture fits perfectly on the mountainous background of the town of Sinaia. The inside contains 160 rooms, which are beautifully furnished and decorated in the German, French Rococco, Italian, and Moorish styles, with finely carved wooden work and stained glass, imported from Switzerland and Germany and dating from the 15th to the 19th century.

The castle halls have on display paintings of the Italian school (Tiepollo, Corregio, etc.), decorative art from the 18th and 19th centuries, more than 4,000 pieces of European and oriental weaponry dating from the 15th to the 19th century, oriental rugs, 18th century Flemish and Aubusson tapestries, etc.
The park of the castle is designed in the style of the late Italian Renaissance and contains fountains and statues brought from Venice. It has terraces covered with decorative and exotic bushes.
