The Peles Castle was built at the initiative of King Carol I of Romania (1866-1914), as the summer residence of the royal family. King Carol I purchased in 1871 a 1,000 hectares estate from Eforia Sitalelor.
In 1873, three hundred workers supervised by architect Wilhelm von Doderer (1873-1876) and by King Carol I, started landscaping the site on which the Peles Castle was built. They had worked hard to master the whimsical elements of nature such as underground watercourses and landslides that destroyed overnight their work. The actual construction began in August 1875.
In 1883, the symbol of the Royal Family, the Peles Castle was officially opened. Its location in Prahova Valley was not random, at that time Predeal was the border with the Austro-Hungarian Empire. After the union of Transylvania with the Old kingdom, the Peles Castle stand in the middle of the country.

The architecture of this style is distinguished by sharp profiles, vertical slender, irregular forms, fragmented composition of facades, asymmetric bodies, carved wood and decorative elements.
