Mount Vernon Mill was a major cotton textile producer in the Jones Falls Valley, starting with Mill No. 1, located in a converted flour mill, in 1850. Capacity was expanded by construction of Mill No. 2 in 1853 and Mill No. 3 in 1873 nearby on Chestnut Avenue. After severe damage from a fire in 1873, Mill No. 1 was entirely rebuilt in brick with a square end tower and decorative corbeling. Mount Vernon was the last textile mill operating in Baltimore when it closed in 1972. Mills No. 2 and 3 were renovated into offices and galleries in 1987, while No. 1 became apartments, offices, and restaurants in 2013. The still extant mill worker’s neighborhood of Stone Hill is located above the Mount Vernon Mills. These small stone company houses were sold to the workers after a strike in the 1920s.
