Fort Bourtange is a remarkable star-shaped landmark built in 1593 in Groningen, Netherlands. Controlled by the Spaniards during the Eighty Years’ war, the fort became a village in 1851, and now serves as an historical museum. The star shape is surrounded by a series of canals and lakes that serve as moats. It’s a fantastic reminder of the power of design and engineering that goes back over 400 years.
