Rockville is a city that serves as the county seat of Montgomery County, Maryland, United States, part of the Baltimore–Washington metropolitan area. The 2010 census tabulated Rockville's population at 61,209, making it one of the largest communities in Maryland and the third largest location in Montgomery County, after Silver Spring and Germantown.
Rockville, along with neighboring Gaithersburg and Bethesda, is at the core of the Interstate 270 Technology Corridor which is home to numerous software and biotechnology companies as well as several federal government institutions. The city, one of the major retail hubs in Montgomery County, also has several upscale regional shopping centers.
Situated in the Piedmont region and crossed by three creeks (Rock Creek, Cabin John Creek, and Watts Branch), Rockville provided an excellent refuge for semi-nomadic Native Americans as early as 8000 BC. By the first millennium BC, a few of these groups had settled down into year-round agricultural communities that exploited the native flora, including sunflowers and marsh elder. By AD 1200, these early groups (dubbed Montgomery Indians by later archaeologists) were increasingly drawn into conflict with the Senecas and Susquehannocks who had migrated south from Pennsylvania and New York. Within the present-day boundaries of the city, six prehistoric sites have been uncovered and documented, along with numerous artifacts several thousand years old. By the year 1700, under pressure from European colonists, the majority of these original inhabitants had been driven away.
The indigenous population carved a path on the high ground, known as Sinequa Trail, which is now downtown Rockville. Later, the Maryland Assembly set the standard of 20 feet for main thoroughfares and designated the Rock Creek Main Road or Great Road to be built to this standard. In the mid-18th century, Lawrence Owen opened a small inn on the road.
