Grebbe Line, Defense line in Utrecht, Netherlands
The Grebbe Line is a defense system made up of fortresses, trenches, and earthen barriers spread across the landscape. These structures include dikes, ditches, and defensive positions that worked together to block and slow down any attacking forces.
The defense system was built beginning in 1745 as a way to protect the region from invasion. It saw heavy use and expansion during World War II when it faced actual attack.
