At first sight, the old wrought iron fence on the corner of P and 28th streets appears indistinct from the many other railings that skirt Georgetown’s redbrick sidewalks. Upon closer inspection, however, it’s clear this fence is unique. Cracks in some of the pickets reveal that although each upright is hollow, the walls of the pickets are far thicker than is structurally necessary for a perimeter fence. Plus, a number of the pickets feature small nubs just below the attached spikes, which, even to the untrained eye, resemble gun sights. While the Gun Barrel Fence has long been a Georgetown landmark, the fence’s origins remain shrouded in mystery and misconception. Let’s bust some myths, shall we?
