If you’e ever driven across the Francis Scott Key Bridge, then you may have spotted this peculiar structure in the Patapsco River. This place is known as Fort Carroll, and it was built in 1847 as a defense spot to protect the city of Baltimore. It was manned during the Spanish-American War and Civil War but soon thereafter, was left abandoned.

Today, Fort Carroll is only home to whatever wildlife has found its way there, including an abundance of migratory birds. You won’t find humans there, except for the rare times when a curious boater or kayaker will make his or her way to the fort for a bit of urban exploring. Luckily, we have footage from one such person.

Check out the below video by Youtube user Explore Baltimore. This neat footage of Fort Carroll captures aerial views, up-close exploration, and a quirky take on Jurassic Park:
