Musée de l'Annonciade

Tucked into Saint-Tropez, the Musée de l'Annonciade is a modern art gem housing works from 1890 to 1950 by the painters — Signac, Matisse, Bonnard — who actually lived and worked in this town when it was still a quiet fishing village. Founded in 1922, it's one of those rare places where the art and the setting genuinely make sense together, giving you a real feel for why the French Riviera became such a creative magnet.
