Ancien hôpital Beaujon, Historical monument in 8th district of Paris, France.

The Ancien Hôpital Beaujon is an 18th-century stone complex built from July 1784 to August 1785 by architect Nicolas-Claude Girardin for the banker Nicolas Beaujon. Its street front forms a quadrilateral about 30 metres wide and 40 metres deep around a courtyard, with a monumental facade pierced at its centre by a wide round-arched portal topped by a coffered vault. The preserved building now houses a crèche, a conservatory and a community centre.

Nicolas-Claude Girardin built the hospice from July 1784 to August 1785 for the banker Nicolas Beaujon, on land bought from the baron d'Arcy between the rue du Faubourg-du-Roule and the rue de Chartres. It housed an orphanage for twenty-four poor children of the parish, twelve boys and twelve girls, who left at fourteen with 400 livres. A decree of 18 January 1795 turned it into a hospital; it moved to Clichy in 1935.

The building shapes the neighborhood with its neoclassical facade and shows how 19th-century Paris designed public structures. Visitors can see in its symmetrical layout how much value was placed on order and clarity in institutional spaces.

The facade is clearly visible from the street and the location is easy to reach by public transport in the 8th arrondissement. The building has protected status, so some areas may not be open for visits.

The building features windows deliberately designed tall and large following medical principles of the era to allow natural ventilation. These details show how architecture and medicine worked closely together to provide patients with a better environment.
