Heartbreaking Photos of Lonely Rowhouses

For many, Baltimore design is synonymous with the rowhouse. Many of the city's neighborhoods are defined by blocks upon blocks of these narrow residential dwellings. Some represent the city's history and beauty, others symbolize decades of widespread poverty and disinvestment.

Baltimore photographer Ben Marcin, who lives in a well-kept rowhouse himself, has been documenting structures that haven't fared nearly as well. In "Last House Standing," started in 2010, Marcin shoots heartbreaking photographs that show neighbor-less rowhouses, its density-friendly architecture surrounded awkwardly by vacant lots.
