The Royal Castle of Racconigi is a palace and landscape park in Racconigi, province of Cuneo, Italy. It was the official residence of the Carignano line of the House of Savoy, and is one of the Residences of the Royal House of Savoy included by UNESCO in the World Heritage Sites list.
The first records of the castle are from around the year 1000, when Bernardino of Susa rebuilt an ancient manor, leaving it to Cistercian monks. The castle was a possession of the margraves of Saluzzo and others starting in the 13th century, and in the 16th century was acquired by the House of Savoy. In 1630, Duke Charles Emmanuel I granted it to his nephew Thomas Francis, Prince of Carignano, founder of the Savoy-Carignano line. At this time, the castle was a high brick moated fortress with a square plan, four corner towers and a tall donjon (mastio) on one side.
Emanuele Filiberto, Prince of Carignano, Tommaso's son, in the late 17th century, commissioned Guarino Guarini to transform the fortress into a pleasure residence. The architect erected the current central section where the court was, adding a pagoda-like roof. The two northern towers were replaced by pavilions with dome roof and square plan, provided with white marble lanterns. The gardens were also created. In the late 18th century, Ludovico Luigi Vittorio of Carignano ordered a renovation of the interiors, enlarging the two southern towers, adding stucco and other neoclassical decoration; he also commissioned a new entrance, with 4 Corinthian columns and a triangular fronton, and the great staircase.
Charles Albert, a Carignano who eventually became King of Sardinia, further enlarged and embellished the castle to represent the splendour of the newly acquired reign. His court architect Ernesto Melano expanded the ancient square structure around the central section, added two side buildings connected to the façade pavilions, as well as another staircase on the southern side.
Emmanuel Philiberto created a magnificent wide park in the jardin à la française style that opens for the castle's northwards view. It was designed by the renowned 17th century by the French landscape architect André Le Notre, known to him for designing the gardens of Versailles radiating from Château de Versailles. In the late 18th century the English Landscape garden style was introduced, Pelagio Palagi erected a series of small structures along the lake; such as the Doric Tempietto, the Gothic style chapel, and other landscape elements. A "Russian dacha," built to honour tsar Nicholas II of Russia's visit to Piedmont in order to sign the Racconigi Bargain, was also created in the landscape park.
