DC alleys and stables were the pulse of the city reflecting the ecology of urban change. Their stories reflect many lives and are living artifacts of 200 years of human experience in Washington. Reconstruction cannot possibly replace preservation. In 1990, all of the properties in Blagden Alley and Naylor Court were recognized by the National Register of Historic Places.
While horse drinking troughs were on almost every block years ago, few people would recognize them today. Sometimes owners add "equine artifacts" to their stable so that passersby can recognize the origin of the building. An example is on the wall of this stable in Georgetown near the Key Bridge.
