Building #302 on South Post. According to a legend-map we have, the 300-series structures were in the south-west portion of South Post, near the intersection of the beginning of Columbia Pike and Arlington Ridge Road. After the Civil War, "Freedman's Villages" were set up around the country to house freed slaves. One was at this exact location.

This appears to be an early-60's view of Seven Pines Street, looking south. The post pool is just out of the photo, near Washington Boulevard, which can be seen in the background, and The Pentagon is barely visible to the above left of the boulevard. The cars are parked in front of Buildings 409 through 412.
