Saint-Martin-du-Tertre (French pronunciation: [sɛ̃ maʁtɛ̃ dy tɛʁtʁ] ⓘ) is a commune in the Val-d'Oise department in Île-de-France in northern France. It was first attested in 1170 as "Sanctus Martinus de Colle".[3]
Between 1876 and 1882, André Philippe Alfred Régnier (1837–1913), 3rd Duke of Massa, had the Château de Franconville (rue Corentin Celton ) built under the direction of architect Gabriel-Hippolyte Destailleur. The Maisons-Laffitte castle served as a model. It was converted into a sanatorium in 1929.
