Palais Carnolès, Historic palace in Menton, France.

Palais Carnolès is a former summer residence of the Grimaldi princes of Monaco on avenue de la Madone in Menton. Built from 1717 and finished in 1725, it follows the model of the Grand Trianon: two two-storey pavilions joined by a portico on the entrance side, with a large Italian-style salon opening onto the garden through three arcades. A balustrade crowns the elevations, and the building was later doubled in depth toward the park by architect Hans-Georg Tersling.

Antoine I of Monaco bought land from the Lérins monks in 1717 and had a Trianon-style palace built there, finished in 1725; Jean Antoine Latour modified the plans and Menton painters Bressan, Puppo and the Vento brothers decorated it. Sold by the prince in 1863, it served as a gambling casino from 1863 to 1876. American Edward Philips Allis Jr. bought it in 1896 and had Danish architect Hans-Georg Tersling enlarge it; it was listed as a monument historique on 12 September 1969.

The name Carnolès comes from the priory of Sainte-Marie de Carnolès, documented as early as 1177. Antoine I of Monaco used the palace to gather his musical ensemble and taught his daughter Marie-Pelline Grimaldi, called the "muse of Monaco", to play the harpsichord there until her death in 1731. The hexagonal baroque kiosk in the grounds has paired pilasters in a variant of the Genoese caryatid order.

The palace stands on avenue de la Madone in Menton, with the museum in the building and the one-hectare botanical park around it; contemporary sculptures have been displayed in the gardens since 1994. The park follows a rectilinear plan, with tall Phoenix canariensis palms lining the main alley, so allow time to walk its length.

The citrus collection is certified by the Conservatoire des collections végétales spécialisées and counted at 137 varieties, among them 24 sweet oranges, six bitter oranges, six lemon trees, mandarins, kumquats and grapefruit trees. Tall Phoenix canariensis palms line the main path. Since 1994 contemporary sculptures have been placed in the gardens.
