Jean-Baptiste Martenot

Jean-Baptiste Martenot (Saint-Seine-l'Abbaye Côte-d’Or 26 July 1828 - 30 March 1906 Rennes), was a French architect, born in Bourgogne, in the city of Rennes. The Halles Martenot and the Préfecture Martenot are names in his honour. He is a former student of the école des Beaux-Arts.

From humble beginnings, he obtained a departmental pension to study at the École nationale des Beaux-Arts in Paris, which he attended until 1850. He won the prix Muller Sœhnée.

At 26, Martenot was named inspector of the Palais du Louvre.

In 1858, the mayor of Rennes Léon des Ormeaux appointed him to the post of chief architect of the city of Rennes, a post he held until 1895.
