515 North Washington Street

515 North Washington Street is a four-story brick building featuring Corinthian columns at its main entrance. It has been extensively renovated and now contains residential apartments called The Mill.

The building was constructed in 1848 as Alexandria's first cotton mill and originally employed around 150 workers. After the factory closed, it served as a prison during the Civil War and later as a brewery before being converted to residential use.

The building served as a center of industry and labor in Old Town Alexandria for generations. Its thick brick walls reflect the different roles it has played in the community's story.

The building sits near King Street Metro Station, offering easy access to Washington DC and surrounding areas. Visitors find it in a walkable neighborhood with shops, restaurants, and other attractions nearby.

A mannequin named Oscar stands in the building's cupola and has remained there through multiple renovations over decades. This mysterious figure is an unusual detail that many visitors overlook.
