The sprawling Cantacuzino Castle (Castelul Cantacuzino) was completed in 1911 to plans drawn up by architect Grigore Cerchez; it was designed as a hunting lodge for Prince Gheorghe Grigore Cantacuzino, who was twice Prime Minister of Romania in the 1900s. Surrounded by forested hills, the mansion has an ornate stone-and-brick façade adorned with colonnaded loggias and towers in an exotic style known Neo-Romanian; it is open for guided tours of the decorative interior, where flourishes of Art Nouveau, patterned marble floors, stained glass, mosaics and embellished carved wood abound. A rare collection of Cantacuzino coats of arms is on display and the castle is host to occasional art exhibitions as well as summertime musical concerts known as Prahova Classic Nights.
After exploring the inner courtyard, the Cantacuzino family church and the hunting tower, there are grottoes and fountains to discover in the gardens and views towards the Bucegi Mountains. Family activities available at the castle include horseback riding, archery, zip lines and an adventure course for young kids. Costs for these sports are additional to admission prices but full instruction and safety gear are provided. Visiting Cantacuzino can be combined with a tour of fairytale Peles Castle in nearby Sinaia.
