Origin and history

The Mont-de-Marsan prison, built between 1807 and 1809 by engineer David-François Panay and Claude Antoine Gagelin, embodies the prison architecture of the First Empire. Built on the site of the former Ursuline convent, which had become a national convent after the Revolution, it met the functional and symbolic needs of a newly created prefecture. Its facade, inspired by the ancient cachots of Piranese, reflected Napoleon's repressive policy, with austerity calculated to inspire fear and respect, despite the initial protests of the bourgeois residents.

The monument is part of a coherent administrative complex, facing the courthouse and the gendarmerie, as evidenced by the cadastre of 1811. The prefect Valentin-Duplantier boasts in 1811 its qualities: perfect safety, integrated infirmary, and a round path facilitating supervision. However, its severe appearance contrasts with the luxurious character of the rue Armand-Dulamon, lined with private hotels like the Brettes. The prison, operating until 2008, became the scene of public capital executions in 1923 and 1931, before being requisitioned during the Second World War by the Germans to intern Jews arrested in the Landes.

During the occupation (1940-1944), the prison served as a place of detention for about 230 Jews, separating children and adults before their transfer to Bayonne, Dax, or the camp of Mérignac. After the Liberation, it briefly welcomed alleged collaborators. Partially classified as historical monuments between 1987 and 2010, only its facade is preserved during its transformation into a "Cœur de Ville" residence in 2019. The entrance porch, staircase and solid wooden door, decorated with bosses and iron rings, illustrate the repressive neo-classical aesthetic of the time.

Architecturally, the facade combines two styles: the eastern part, a work by Panay (1807-1809), features harpy angle chains and a monumental door with bossed harps, while the western part, added by Arthaud (1820-1823), adopts a sober classicism with blind bays curved on the ground floor. Materials, such as rustic bossing, reinforce its intimidating appearance. After 1945, the prison remained active until the execution of René Discazeaux in 1947, the last benevolent of the Landes, before its final closure in 2008.

A symbol of judicial and urban change, the site today embodies the memory of the violence of the twentieth century. The 31 hostages of Granada-sur-l'Adour, arrested in 1944 for resistance, were interrogated there before their deportation to Dachau. After the war, the prison also illustrates the evolution of capital punishments, with the transition from public executions (1923, 1931) to discreet killings in the court (1947). Its partial classification in 1990 underscores its heritage value, despite the disappearance of the interior buildings.
