Permanent exhibition –
The English hospital

Three days from 15 to 18 June 1815…
Mont-Saint-Jean Farm owes its listing as a heritage site by the Walloon region and its worldwide fame to the role it played in the Battle of Waterloo during this short period.

The Duke of Wellington decided to set up a field hospital in this building. Under the command of Deputy Inspector Gunning of the Royal Army Medical Corps, approximately 6,000 soldiers were treated in this makeshift hospital. According to contemporary eyewitnesses, countless lives were saved thanks to the proximity of this medical facility where the amputated limbs “piled up in the four corners of the farm’s courtyard”.


Several important historical figures
who fought at Waterloo are mentioned in the patient register of Mont-Saint-Jean hospital: Colonel William Delancey and Lieutenant Colonel Alexander Gordon, aides-de-camp to the Duke of Wellington, the Duke’s secretary (and nephew) Lord FitzRoy Somerset and William, the Prince of Orange, who was injured in the shoulder. To honour the bravery of Army Surgeon John Gunning and his team during the battle, an exhibition will focus on the events that transformed Mont-Saint-Jean Farm into a British Field Hospital.

Particular attention will be devoted to the women who played a crucial part in the patients’ survival, all too often forgotten by history. This is also the ideal occasion for visitors to learn more about field hospitals, without which countless wars would have cost considerably more lives. And since Mont-Saint-Jean Farm had already been an importance site well before 15 June 1815, we have decided to provide an overview of other great historical moments in this exhibition: its occupancy by the Knights Hospitaller (the future Order of Malta),
its strategic position at other battles, its agricultural activities and its brewing history.
