Château de la Moutte, Heritage castle in Saint-Tropez, France.

Château de la Moutte is a two-storey ochre-yellow building with a red-tiled roof edge and a central round tower with a crenellated top, fronted by a projecting bay. The symmetrical facade has tall shuttered windows with reddish-brown slatted shutters and stone surrounds, and a central doorway with a carved stone frame reached by a few steps. A decorative perforated parapet runs along the roofline, and a carved panel above the door reads "CHATEAU DE LA MOUTTE".

The bastide was bought in 1860 from the Martin de Roquebrune family by Émile Ollivier, last head of government under Napoleon III, who settled there with his first wife Blandine Liszt, daughter of Franz Liszt and Marie d'Agoult. He had his motto, "Certa viriliter sustine patienter", carved on the entrance pediment. He withdrew there after the war of 1870. The estate passed to his descendants.

In 1975 Anne Troisier de Diaz, granddaughter of Émile Ollivier, started a summer music festival, the Nuits du château de La Moutte, hosting artists for nearly thirty years in the courtyard of the house. Pianists Michel Dalberto and France Clidat and conductor William Christie performed there. A festival of Nuits musicales continues today.

The château opens to the public during the Journées du Patrimoine, France's annual heritage days; the estate has been managed by the Conservatoire du littoral together with the town of Saint-Tropez since 1998. The entrance door is reached by a few steps and framed by carved stone, with the inscription panel above it.

On the entrance pediment Émile Ollivier had his motto carved: "Certa viriliter sustine patienter". The inscription panel above the door still reads "CHATEAU DE LA MOUTTE". His granddaughter Anne Troisier de Diaz, who kept the house in its original state, gave Ollivier's archives to the Archives nationales and bequeathed the estate to the Conservatoire du littoral in 1998.
