Collège Bellefonds, School building in Rouen, France

Collège Bellefonds stands at 161 rue Beauvoisine in Rouen, its weathered stone and plaster facade topped by a dark slate roof with seven dormer windows. Two rows of six tall rectangular windows light the upper floors, with two narrower openings at the outer edges of the lower row. A yellow pipe angles up the left side; at ground level a white sign reads "Collège Bellefonds" beside a red "ALTRAD" banner.

The site experienced two main phases: first as a Benedictine convent established in 1648, later transformed into a school founded in 1862 by the Christian Brothers. This educational function shaped the area for more than 140 years before institutional changes began in 2009.

The name Bellefonds comes from Laurence Gigault de Bellefonds, superior from 1648 of a Benedictine community she moved from the faubourg Saint-Sever into Rouen; her nephew, the Maréchal de Bellefonds, helped fund the convent built in 1653–1655. The site later housed a theatre from 1823 and a boarding school before the Christian Brothers arrived in 1862.

The site sits in a central urban area of Rouen with good access via the city's street network. Since the buildings have been converted to residential apartments, the interior is not open to visitors, but the exterior facades remain visible from the street.

The convent church, consecrated to Notre-Dame-des-Anges, was built between 1674 and 1677 and destroyed after 1796, when the sale of the community's property dispersed its goods. The site was split into two lots: the cloister buildings around which the Brothers settled in 1862, and the former girls' boarding school courtyards to the south.
