Cantacuzino Castle is located in Bușteni, Romania. Built in 1911 in the Neo-Romanian style for Prince George Grigore Cantacuzino, it has over 3,000 square meters and is surrounded by a park with fountains and a waterfall grotto. During communist rule, the castle was used by the government and its interior altered, but it was restored after 1989 and is now open to the public.
