Thézan was the first community in France to take the decision to erect a memorial to the memory of those who fell in the 1914-1918 war.

The War Memorial, a work of the sculpter Magrou, a follower of Injalbert, was built following a decision of the town council on the 21st March 1919. Indeed previously on the 24th december 1914 the town council has already taken the decision to raise a monument to the soldiers killed during the war. It followed the announcement, ar the very beginning of the conflict, of the death of the first two Thézan victims, private François Sauzet, aged 22 and corporal René Lentheric, aged 31 and a member of the town council.
In 1923 it was fenced around with a lattice work of iron bars made by Damien Baronnet a metal smith from Thézan. 59 people from Thézan have died during conflicts throughout the world.
