Among Sisley's best-known works are "Street in Moret" and "Sand Heaps", and "The Bridge at Moret-sur-Loing" shown at Musée d'Orsay, Paris. "Allée des peupliers de Moret" ("The Lane of Poplars at Moret") has been stolen three times from the Musée des Beaux-Arts in Nice. The first time was in 1978 when on loan in Marseille, but it was found a few days later in the city's sewers. It was stolen again in 1998 and the museum's curator was convicted of the theft and jailed for five years along with two friends. It was stolen again in August 2007. On 4 June 2008, the French National Police found it and three other stolen paintings inside a van in Marseille.
