Prison du Pré-Pigeon, Historical prison in Angers, France.

Prison du Pré-Pigeon is a remand centre in Angers whose stone and brick facade carries three polygonal towers, one central and one on each side, beneath a flat roofline. Rough grey and brown stone alternates with patches of pale plaster and smooth brownish blocks; each tower has narrow vertical openings. A light grey double door with a small square window, set in an arched stone surround above a short flight of steps, forms the entrance, with a tricolour flag on a tall pole above it.

Built between 1852 and 1856 by architect Ferdinand Lachèse, it replaced earlier prison installations that had operated within Château d'Angers. This shift to a dedicated facility marked a major change in how the city approached incarceration and detention practices.

The prison's nickname, Pré-Pigeon, comes from the plot where it was built. From 1902 to 1948 Canon Uzureau served as its chaplain. The central surveillance post is topped by the prison chapel, and the monumental entrance takes the form of a small châtelet, details a visitor can pick out from the street.

The facility is located near Place Olivier-Girau in central Angers and remains an active detention center. Access may be limited since it continues to function as a working prison rather than a museum or tourist site.

The German occupiers evacuated the prison on 6 August 1944, taking with them a final convoy of 134 deportees. Many resistance fighters had been held and tortured there before deportation or execution on site. The building is inscribed as a monument historique since 1997, including its four cross-shaped wings and central rotunda.
