Busteni is a small mountain town in the north of Prahova county, in the center of Romania. It is located in the Prahova Valley, on Bucegi Mountains.
Cantacuzino Castle was built in 1911 in the park owned by the Prince and is one of the top castles in Romania in terms of architecture. During the communist regime, the castle was nationalized and transformed in a TB sanatorium of the Ministry of Internal Affairs; after 1989 it was returned to the heirs of the Prince, who sold it in 2004 to a group of investors that restored it and reinstated in the tourist circuit.
