Two kilns remain in the woods to the west of Marriottsville Road between the B&O railroad and the bridge over the Patapsco. The front wall of the one on the left had collapsed, but the 20 foot tall kiln to the right (west) is fairly intact and part of Patapsco Park. The limestone was quarried nearby.
