 During WWI the citizens of Pesche also went out to fight, and a statue in their honor was built in April of 1920, the first in all of Molise.During that time the biggest influence on the town was religion and the church lead by the Arch priest don Zeffirino Petrecca, who fought to maintain things as they were during his time and kept to the origins and traditions of the town.In the 1950s several trees were planted in the hills, which today make up the Pine forest, that functions as a fortress for the unstable stones around the town that are sedimentary and are on a clayish terrain.
