1908 Map of Rockville

About this map

Rockville and Gaithersburg serve as the primary hubs in this early twentieth-century survey of Montgomery County, Maryland. The landscape is defined by a dense network of country roads and historical turnpikes, including the Union Turnpike and Frederick Road, which connect a series of established rural settlements like Laytonsville, Sandy Spring, and Brookeville. The Baltimore and Ohio Railroad (Metropolitan Branch) cuts diagonally through the territory, marking the growth of commuter and industrial corridors at places like Derwood and Washington Grove. To the southwest, the Potomac River forms a dramatic boundary at Great Falls, while the northeastern portion shows the Patuxent River bordering the now-submerged site of Triadelphia. This map captures the region when it was still characterized by scattered schools like the Academy, family-named branches, and a distinct agrarian social structure before the mid-century expansion of the capital region.
