1923 Map of Rockville

About this map

Rockville stands as the central hub of this Maryland landscape, captured during a period of steady transition from rural agriculture to commuter proximity. The Baltimore and Ohio Railroad slices diagonally across the terrain, linking key settlements like Gaithersburg, Washington Grove, and Derwood. The upper portions of the map reveal a dense network of farming villages and crossroad communities such as Laytonsville, Olney, and Sandy Spring, many of which maintain their historical character today. Notable institutional landmarks are present, including the National Park Seminary and the Montgomery Country Club, reflecting the early 20th-century development of the region's social and educational infrastructure. Waterways like Great Seneca Creek and the Hawlings River define the drainage patterns of the rolling countryside, while the Potomac River forms the southwestern boundary, providing a glimpse into the river-and-rail economy that shaped Montgomery County before the mid-century suburban expansion.
