515 North Washington Street, Historic cotton mill building in Old Town Alexandria, United States.

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 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.
