The Wentworth Drive school roped in staff, parents, governors and generous trades people to create the trench.
It is now being used to teach the children about life in the First World War.
Head teacher David Edwards said “This was a fantastic project to be involved with.
"We were overwhelmed by the support, help and donations we received from not just present parents and staff but also the community and trades too.
“The whole thing was completed at no cost to the school.
"It just shows what can be achieved for the benefit of the children with an active PTA, good communications by the school office, the generosity and assistance of supportive parents and the children’s imaginations.
“The design changed several times during construction and there were a few delays but through it, the children were very excited by it all as some had already studied the First World War earlier and were even writing their own dramas to perform in and around the trench.
“The trench is an iconic symbol of the conflict but I wasn’t aware until the school started showing me their research how much the way lives changed an incredible amount because of it.”
