Its fortress like Buildings were built to keep out the blight that had become Downtown Baltimore. Mount Vernon is north of Charles Center and since it hadn't entered into decline, the stark difference between new and old, thriving and blighted was not so apparent. Whether or not this was intentional, the west of Mount Vernon had become like the Westside of Downtown though it borders Bolton Hill. This is what I refer to as the "Midtown Donut" where it's a dead zone that "connects" Bolton Hill to Mount Vernon though it's uncharacteristic of both Neighborhoods.
One big mistake that was made in the Charles St. Streetscape enhancements was that in the repaving proccess trolley tracks weren't added in for future use. Above I-83 Station North is making a huge comeback with more plans in the way. Mount Vernon and Charles Village will be connected once more. The dead Midtown Donut is attempting to be "filled."
