Messines Ridge Memorial, World War I memorial site in Mesen, Belgium

Messines Ridge Memorial is a stone monument in Belgium listing 827 names of soldiers who died during World War I in this region without known burial places. The site consists of stone panels designed by a notable architect and sits near the village of Mesen.

The memorial, designed by English architect Charles Holden, stands on the site of the Moulin d'Hospice, a mill dating from 1445 that belonged to the Institute Royal de Messines and was destroyed in the war. It commemorates 827 New Zealand soldiers with no known grave who fell in or near Mesen in 1917 and 1918. The nearby white stone obelisk was unveiled by King Albert I on 1 August 1924.

The memorial bears names of soldiers from a nation thousands of miles away in the southern hemisphere who fought in this conflict. These inscriptions show how far the war reached and how people from distant lands died in this place.

The memorial stands within Messines Ridge British Cemetery, entered through a curving forecourt between two low stone walls inscribed "MESSINES RIDGE" and "BRITISH CEMETERY". A paved path crosses dark gravel to the Cross of Sacrifice. The grounds are open year-round; the path and gravel can be wet or muddy after rain.

The memorial stands on the site of the Moulin d'Hospice, a mill dating from 1445 that belonged to the Institute Royal de Messines, a Belgian orphanage and school once a Benedictine abbey. The mill was destroyed in the war, and the memorial was built where it stood.
