Many international airports have interesting histories, but only the one in Richmond can claim fame to being built on a series of Civil War earthwork fortifications, some of which survive to this day.
At the time of the American Civil War, the Virginia capital was surrounded by a series of three expanding rings of earthwork fortifications: earthen berms and ditches that were defended by infantry and artillery. These earthworks were designed to allow the Confederate troops to hold off numerically superior Union forces.
The Richmond earthworks saw several pitched battles, and were the site of one of the first uses of aviation in combat, when Civil War aeronaut Thaddeus Lowe ascended in a balloon during the battle of Seven Pines in 1862 to observe these very fortifications for weaknesses.
You can still see traces of the Richmond defenses today, over 150 years after the end of the war. They were rediscovered when the Richmond International Airport access road was laid, and the city placed several markers and cannons to mark the locations. Now, these cannons guard the city, pointing out across what was formerly battleground, and now airport runways.
Know Before You Go
It may be possible to park on the shoulder of the road (Airport Drive) at points to view the fortifications, but expect possible attention as this is immediately next to the Richmond Airport.
