Where was the western front where much of the fighting took place?

The Western Front was primarily located in northern and western France and Belgium during World War I. It stretched from the North Sea in Belgium down to the Swiss border, serving as the main theater of war between the Allies and Central Powers. This front became infamous for its trench warfare, which resulted in significant casualties and stalemates over several years. Key battles, such as the Battle of the Somme and the Battle of Verdun, occurred in this region.
