A war memorial is a structure or MONUMENT dedicated to commemorate those who died or were injured in a war. The most common type of war memorial is a CENOTAPH, which is an empty tomb or a MONUMENT erected in honour of a person or group of people whose remains are elsewhere. A MONUMENT is a structure built to commemorate a person or event, often with a plaque or inscription. Both cenotaphs and monuments are used as war memorials to remember those who have died in war.
