When the Royal Naval Hospital opened on the edge of Stonehouse Creek in 1760, hospital architects everywhere quietly took note. Instead of one long building with wards strung end to end, the Plymouth design scattered ten detached ward blocks around a vast quadrangle, each pavilion separated by open space so that air could move and infection could not. The French anatomist Jacques-Rene Tenon, who visited in 1787 and published his findings in 1788, called it the most perfect hospital for its intended purpose that we have known. The hospital reformer John Howard praised it. The physicist Coulomb praised it. A full century before Florence Nightingale popularised the pavilion plan in Britain, Plymouth had already built it - and built it from limestone, granite, and the strong opinions of an unnamed Royal Navy commissioner.
The site sat on the edge of Stonehouse Creek, in marshy ground formerly known as the mill fields after the tide mills along the water. It was, by design, isolated - well separated from the village, close enough to the dockyard to receive sailors directly by boat, distant enough that the Navy could control who came and went. The hospital was the second of its kind in Great Britain: the first, at Haslar near Portsmouth, had opened seven years earlier with the older ward-end-to-ward-end design. Stonehouse's planners broke with that pattern completely. Their quadrangle was ringed with separate three-storey blocks, each connected to its neighbours only by a covered colonnade at ground level. A patient with a contagious fever could be isolated in their pavilion without endangering the rest. Cross-breezes flushed every ward independently. Architectural historians have since called the design revolutionary, pioneering, and of international importance.
The central block in the main quadrangle still carries the cupola with its original clock - a 1776 Grignion and Son movement, made in Covent Garden, still keeping naval time more than two centuries later. Behind that cupola the hospital ran itself as a small self-contained settlement. Four senior officers (the surgeon, physician, steward and agent) lived together in a 1763 terrace of houses west of the quadrangle, and together formed the governing Council that answered to the Sick and Hurt Board in London. The Physician was, perhaps surprisingly, the chief officer - in 1760, medicine still outranked administration. Behind the terrace were stables and houses for two clerks who assisted the agent and steward. A pair of lodges flanked the gates, holding the offices of the men responsible for the money, the stores, the food, and the personnel.
In 1795 the Admiralty added something the original plan had not bothered with: military oversight of the patients themselves. A Governor, a post-captain by rank, was appointed to keep order among the sailors recovering in the wards, with two Lieutenants as his deputies. None of these men had any medical role. They existed solely to remind convalescent sailors that they were still subject to the Articles of War. In 1804 two new sets of residences appeared on the green - one for the Governor and a second physician, one for a second surgeon and the two Lieutenants. A separate chaplain's house went up nearby. Royal Marines guarded the gate from a barracks just outside, sister to the Stonehouse Royal Marine Barracks down the road. Later, the police took the job over and the barracks became a police station.
Through the Napoleonic Wars the hospital was a small city of medicine and discipline: two physicians, two surgeons, two assistants of each, an agent, a steward, a chaplain, a dispenser, and between fifty and one hundred untrained female nurses depending on the size of the patient population. The washing of patients - the actual bodily work of nursing - was assigned to male labourers, who also did everything else around the site. In 1854 the Navy expelled the female nurses entirely and replaced them with naval pensioners: old sailors paid a small bonus to act as orderlies. Contemporary accounts called them kindly but rough-and-ready male nurses. Thirty years later they too were swept aside, this time for trained nursing sisters and the new sick berth staff branch - a proper professional cadre of naval medics.
Defence cuts caught up with Stonehouse in 1993. The Options for Change review marked it for closure along with most of Britain's other military hospitals. The closing ceremony took place on 15 March 1995, after 235 years of treating sailors. The eastern end of the site, including the chapel and surrounding buildings, was taken over by St Dunstan's Abbey Girls' School, which merged into Plymouth College in 2004 and used the buildings as a preparatory school until 2021. A new school opened in the historic buildings in 2023 after a 12.5 million pound restoration. The 26-acre main quadrangle, with its detached pavilions and its 1776 cupola clock still chiming, has been turned into a gated residential complex called The Millfields - the same name those marshy mill fields carried before the Navy arrived in 1758. The pavilions that once isolated typhus cases now contain luxury flats.
The former Royal Naval Hospital sits at 50.372 deg N, 4.158 deg W on the Stonehouse peninsula, immediately north of Stonehouse Creek. From the air, the main 26-acre quadrangle with its symmetrical detached pavilion blocks remains clearly readable - one of the most distinctive Georgian footprints in Plymouth. Best viewed from 3,000-4,000 ft. Exeter (EGTE) is the nearest active commercial airport, 40 nm to the east-northeast.
