The Abergele War Memorial is dedicated to honoring the gallant men from the parish who gave their lives in World War I (1914-1918). It serves as a lasting tribute to their sacrifice and is part of a broader effort to document war memorials across various counties.

Additionally, Abergele had a significant moment in history known as "Abergele's Blackest Day of the War," which involved soldiers from the area who fought in Gallipoli in 1915. Many of these soldiers were part of the Royal Welsh Fusiliers, and their names were recorded in local rolls of honor.
