Mount Vernon Triangle Historic District

Mount Vernon Triangle

The Mount Vernon Triangle Historic District is a physical remnant of a unique 19th and early 20th century working class neighborhood that was largely dependent upon the commercial activity of the Northern Liberties Market and 7th Street corridor. The collection of historic buildings provides a visual reminder of the types and scale of homes and businesses that were erected by members of this community—working class entrepreneurs of mixed backgrounds, including a sizeable German and Italian immigrant population, many with ties to the local merchant community. The district also includes archaeological resources and buildings documenting the beginnings of automobile service businesses. In this Historic District there are 24 contributing buildings from 1873-1946.
