The Waterloo Battlefield is located in the municipalities of Braine-l'Alleud and Lasne and Waterloo, about south of Brussels, and about from the town of Waterloo. The ordering of the places in the list is north to south and west to east.
North of the line of battle
Sonian Forest——lies to the north of the battlefield on the approach to Brussels. Napoleon Bonaparte in Mémoires pour servir à l'histoire de France en 1815, avec le plan de la bataille de Mont-Saint-Jean repeatedly criticised the Duke of Wellington's choice of battlefield because of the forest to his rear. For example on page 207 — "The position of Mont-Saint-Jean was ill-chosen. The first requisite of a field of battle, is, to have no defiles in its rear. The injudicious choice of his field of battle, rendered all retreat impossible". This criticism has itself been criticised, with various explanation as to why Bonaparte was wrong. Waterloo, Belgium — —It is now a small town, but at the time of the battle it was a village in which most of the senior Anglo-allied officers were billeted the nights before and after the battle. It was here that Wellington wrote his after battle report (dispatch to Lord Bathurst, 19 June 1815). The inn in which Wellington stayed was located opposite the Church of Saint Joseph and is now the Wellington Museum (). The farm of Mont-Saint-Jean, Waterloo——is slightly to the south of the hamlet of the same name and is located on the plateau behind the battle line. Mont-Saint-Jean was the name given to the battle by Napoleon.
Western end of the line of battle
Châteaux Hougoumont——A large farmhouse held by the British Guards throughout the day in a battle within a battle. Wellington described the closing of the gates after the French had broken into the courtyard to be the single most significant event to happen during the Battle of Waterloo, and it is the subject of the memorial to the British Army, placed just outside the gates that was unveiled on 17 June 2015. Lion's Mound——A memorial built shortly after the battle. A panoramic view of the battlefield can be seen from its summit.
Centre of the line of battle
The Waterloo Elm—— Located just south west of the intersection of the sunken lane and the Genappe–Brussels main road, the Waterloo Elm was Wellington's command post for much of the battle. The tree was killed by souvenir hunters after the battle. It was felled in 1818 and made into furniture, which included a chair presented to George IV that remains in the British Royal Collection. La Haye Sainte– —A farmhouse and a key bastion for the defence of Wellington's line held by about 400 riflemen of the Kings German Legion. It was eventually captured by the French.
Eastern end of the line of battle
The following four locations provided the eastern bulwark of the Anglo-allied line: Papelotte — — A hastily fortified farmhouse similar to La Haye Sainte La Haye, Lasne — — A hastily fortified farmhouse less than to the east of Papelotte, but its farmyard was not fully enclosed. Smohain — — a hamlet in a defile which on the day of the battle contained a marshy stream swollen by the overnight rain. Châteaux Frischermont — — A hastily fortified châteaux similar to Hougoumont but not so heavily defended.
