Adélaïde-Hautval Hospital (French: Hôpital Adélaïde-Hautval) was a public hospital in Villiers-le-Bel, in the Val-d'Oise department of France. Operated by the Assistance publique – Hôpitaux de Paris (AP-HP), it opened in 1965 under the name Hôpital Charles-Richet and specialised in elder care. The hospital formed part of the Hôpitaux Universitaires Paris Nord Val de Seine group and offered 285 beds across acute care, rehabilitation, long-term care, and EHPAD services before its closure in 2019. Originally named after the Nobel Prize-winning physiologist Charles Richet, the hospital was renamed in 2015 following public controversy over Richet's support for eugenics and racist theories. After an internal review, AP-HP concluded that Richet's published views were incompatible with the values of the public healthcare system. The hospital was subsequently renamed in honour of Dr Adélaïde Hautval, a French physician recognised for her resistance during the Nazi occupation and her defence of Jewish patients at Auschwitz. The hospital ceased all clinical services in 2017, but the site continued operating as a transitional EHPAD until late 2021, when it was closed due to infrastructure deficiencies and the high cost of renovation. In 2023, a new 7,300 m² multiservice gerontological platform was inaugurated on the same grounds by the non-profit operator ARPAVIE. The facility includes a 110-bed EHPAD, day centres, caregiver support services, and home care programmes. In parallel, parts of the former hospital site were sold to Grand Paris Aménagement and are being redeveloped into an eco-district with 370 housing units, scheduled for completion in 2028.
