Lone Tree Cemetery, Military cemetery in Wijtschate, Belgium.

Lone Tree Cemetery is a Commonwealth War Graves Commission burial ground at Spanbroekmolen, on the Messines Ridge in Wijtschate, Belgium. It was designed by John Truelove and covers 616 m² in a blunt-angled L shape, enclosed by a brick wall with a Cross of Sacrifice at its centre. The cemetery commemorates 88 British soldiers, nine of them unidentified.

The cemetery was established in 1917 to honor soldiers who fell during the Battle of Messines, a major engagement on the Western Front. Belgium permanently granted the land to the United Kingdom as recognition of the sacrifices made by Commonwealth forces in defending the country.

The cemetery takes its name from Lone Tree hill at Spanbroekmolen, the site of the mine blown on 7 June 1917. Sixty of the 88 dead belonged to the Royal Irish Rifles of the 36th (Ulster) Division, killed by that explosion after leaving their trenches at 03:10. Captain Henry Gallaugher of the Royal Inniskilling Fusiliers, awarded the DSO, and Lieutenant Alban Hudson of the Worcestershire Regiment, awarded the Military Cross, are commemorated here.

The cemetery sits on elevated ground with good views across the surrounding hills and is accessible on foot via local paths. Visitors should wear comfortable shoes since the terrain is rolling and weather conditions can change quickly.

Nearby stands a large crater formed by a British mine explosion during the battle that remains clearly visible today. This scar in the landscape serves as a physical reminder of the destructive power of the mining operations used during the conflict.
