Collège de l'Immaculée-Conception, Historic school in 15th arrondissement of Paris, France.

The Collège de l'Immaculée-Conception occupies a long stone building at 391 rue de Vaugirard and 1 rue Lacretelle, with a pale beige facade and grey slate roofs. Its main wing has three levels: tall arched windows on the ground floor, rectangular windows between fluted pilasters on the middle floor, and small square windows under a steep mansard roof with dormers. A taller pavilion with a dome and finial rises at the right end, fronted by a lower structure with a pyramidal slate roof.

The college opened after Abbé Poiloup handed his Vaugirard school to the Jesuit fathers, who made it the Collège de l'Immaculée-Conception at 391 rue de Vaugirard. Henri de Gaulle taught there and his son Charles was a pupil for several years, as were Georges Bernanos and Jean de Lattre de Tassigny. After the complex was divided, part of the buildings was demolished for the Lycée autogéré de Paris; the chapel and dormitory wings were inscribed as monuments historiques on 2 October 1990.

The name refers to the Immaculate Conception, the Marian doctrine to which the Jesuit college was dedicated. Among the pupils were Georges Bernanos, Jean de Lattre de Tassigny and Charles de Gaulle, whose father Henri de Gaulle taught here. The former chapel now serves as a lecture hall for Panthéon-Assas University, and the dormitories house tutorial rooms.

The former chapel and dormitory spaces now serve university functions and are not open to the public, so visitors should appreciate the exterior architecture and street-facing facades. The site sits in a residential neighborhood, so it is best to walk slowly and observe the architectural details.

The chapel and dormitory sections received official recognition as historical monuments on October 2, 1990, emphasizing their architectural and cultural value. This protection helped preserve the original structures from modern alterations.
