La Belle Alliance is an inn situated a few miles south of Brussels in Belgium, chiefly remembered for its significance in the aftermath of the Battle of Waterloo (18 June 1815).
There are two plaques on the building: one is "In memory of the French Medical Corps who attended the wounded with devotion on 18 June 1815"; and the other commemorates the meeting of the two victorious field marshals at the end of the Battle of Waterloo.
The building is currently used on Friday and Saturday evenings as a night club.
After the Battle of Waterloo, at around 21:00, Prince Blücher and the Duke of Wellington met close to the inn signifying the end of the fighting. There is a large mural within the Palace of Westminster painted by Daniel Maclise in 1861 that depicts the meeting taking place at La Belle Alliance.
Blücher, the Prussian commander, suggested that the battle should be remembered as la Belle Alliance, to commemorate the European Seventh Coalition of Britain, Russia, Prussia, the Netherlands, Sweden, Austria, Spain, Portugal, Sardinia, and a number of German States which had all joined the coalition to defeat the French Emperor. Wellington, who had chosen the field and commanded an allied army which had fought the French all day, instead recommended Waterloo, the village just north of the battlefield, where he himself had spent the previous night. Nevertheless, in 1815 the Rondell plaza in Berlin was renamed Belle-Alliance-Platz to commemorate the victory.
