I’ve stopped a couple times on the old alignment of the National Road, just to the east of New Market, Maryland. The road was moved to go around an exit for Interstate 70, but the old road bed remains open to vehicular travel.
There’s a 1920s-30s concrete bridge, but other than that, there isn’t much to see. At least that’s what I thought.
When I stopped on this bit of road on Friday, I noticed the stone structure shown above, just a bit to the north of the bridge. I was surprised, as I would think I would have seen something like this before.
I approached the building. It appears to have been constructed during the first half of the 19th century. This view is taken from the southeast, looking northwest. A small window is visible on the east wall.
Outside, parallel with the front of the structure, a few feet to the south, is this construction. It appears to be covering a spring, though no water was present when the photograph was taken. Perhaps the water flowed out of this spring and into the structure.
