The Hôtel-Dieu of Paris: Nineteenth-Century Reconstruction and Clinical Teaching

The Hôtel-Dieu de Paris was long closely connected with Notre-Dame and the Seine on the Île de la Cité. Its medieval buildings developed along the island’s southern bank and later extended across bridges to the left bank. It received poor, infirm and sick people, combining religious charity with medical care. Augustinian sisters provided nursing over many centuries, while physicians and surgeons gradually developed professional services within the institution.

Its administration changed as the hospital grew. In 1505, the Parlement of Paris entrusted its finances to eight lay commissioners. During the French Revolution, it entered a unified hospital administration. By the nineteenth century, it was an important centre for treating acute illness and teaching medicine, activities that continued through its later reconstruction.

The old hospital suffered several fires. The major fire of December 1772 destroyed much of its accommodation on the island. Debate followed over whether to retain the site, move elsewhere or distribute its functions among other hospitals. A decision in 1781 preserved the Hôtel-Dieu and allowed repairs and rebuilding on the existing foundations.

In the early nineteenth century, the old institution occupied buildings repeatedly altered over time and crowded onto both sides of a narrow stretch of river. Wards, supplies and circulation competed for space. Relocation eventually became part of Paris’s wider urban reconstruction: the hospital needed new accommodation, while the area around Notre-Dame was being redesigned with a more open square and reorganized streets.

Napoleon III and Georges-Eugène Haussmann, prefect of the Seine, kept the hospital near Notre-Dame but moved its main buildings to the former Ursins quarter north of the cathedral square. The supervisory committee’s deliberations and a decree of 22 May 1865 established the new project. Gilbert and Diet contributed to the architectural design, and demolition of the old neighbourhood began a construction programme lasting several years.

The choice involved both medical accommodation and the appearance of the city. The hospital acquired a more coherent complex on the island, while removal of the old hospital opened views and enlarged the space around Notre-Dame. Building the new site also demolished the Ursins neighbourhood, changing streets and residential space north of the cathedral.

The new hospital adopted a double-comb plan: two roughly north–south main buildings each connected to three outward-projecting ward wings, with a courtyard between them. The entrance court could accommodate ambulances, and galleries linked the wards, giving patients, staff and supplies more clearly organized routes through the complex.

The original wards occupied three storeys, with ceilings approximately seven metres high. This height, the courtyards and window arrangements reflected nineteenth-century hygiene’s emphasis on circulating air, when polluted air and miasmas were often regarded as causes of infectious disease. Large shared wards remained, but individual beds and separate male and female wards altered the daily hospital environment alongside changes in nursing.

The Hôtel-Dieu provided clinical teaching before the new hospital opened. Armand Trousseau combined his post as professor of clinical medicine at the Paris medical faculty with work as a hospital physician, and his courses were later collected in print. The 1868 English edition preserves his method of revisiting ward cases with students, comparing observations and discussing the grounds for diagnosis.

The opening lectures, for example, connect patients’ courses in the Sainte-Agnès and Saint-Bernard wards with later pathological examinations. His lecture on aphasia observes that distinctions which appear slight in writing can become more recognizable at the bedside. Teaching depended on observing patients together, following illness over time and comparing cases; published lectures carried those experiences beyond the hospital.

The AP-HP archival guide distinguishes two dates: the new Hôtel-Dieu entered service on 30 July 1877, and President MacMahon inaugurated it on 11 August. Building work and demolition of the old hospital continued into subsequent stages. Some old buildings on the left bank remained in use as an annexe for considerably longer.

Relocation concentrated the main hospital north of the Notre-Dame square, while part of the old left-bank accommodation remained an annexe until 1909. The new complex continued established medical and nursing organization, patient care and teaching, while courtyards, ward wings and individual beds changed everyday operations. Changes to the site and buildings gradually took effect in admissions, inpatient care and teaching.
