History & geography

History

Bethesda is located in the traditional territory of the indigenous Native Piscataway and Nacotchtank at the time of European colonization. Fur trader Henry Fleet became the first European to visit the area, reaching it by sailing up the Potomac River. He stayed with the Piscataway tribe from 1623 to 1627, either as a guest or prisoner (historical accounts differ). Fleet eventually secured funding for another expedition to the region and was later granted proprietary rights to 2,000 acres of land in the nascent colony and became a member of Maryland's colonial legislature. Raids from the Senecas and Susquehannock resulted in the creation of the Maryland division of Rangers in 1694 to patrol the frontier. By 1862, a small settlement had grown around a store and tollhouse along the turnpike known as "Darcy's Store" for the store's owner, William E. Darcy. It consisted of a blacksmith shop, a church and school, and a few houses and stores. In 1871, postmaster Robert Franck renamed the settlement for the church. A streetcar line was established in 1890 and suburbanization increased in the early 1900s, and Bethesda grew in population. Communities near railroad lines had grown the fastest during the 19th century. Subdivisions began to appear on old farmland in the late 19th century, becoming the neighborhoods of Drummond, Woodmont, Edgemoor, and Battery Park. Farther north, several wealthy men made Rockville Pike famous for its mansions. These included Brainard W. Parker ("Cedarcroft", 1892), James Oyster ("Strathmore", 1899), George E. Hamilton ("Hamilton House", 1904; now the Stone Ridge School), Luke I. Wilson ("Tree Tops", 1926), Gilbert Hovey Grosvenor ("Wild Acres", 1928–29), and George Freeland Peter ("Stone House", 1930). In 1930, Armistead Peter's pioneering manor…

Geography

According to the U.S. Census Bureau, the CDP has a total area of , of which is land and (0.38%) is water. The main commercial corridor that passes through Bethesda is Maryland Route 355 (known as Wisconsin Avenue in Bethesda and as Rockville Pike and Hungerford Drive in more northern communities), which, to the north, connects Bethesda with the communities of North Bethesda and Rockville, ending, after several name changes, in Frederick. Toward the South, Rockville Pike becomes Wisconsin Avenue near the NIH Campus and continues beyond Bethesda through Chevy Chase, Friendship Heights and into Washington, D.C., ending in Georgetown. The area commonly known as Downtown Bethesda is centered at the intersection of Wisconsin Avenue, Old Georgetown Road and East-West Highway. This intersection is about two and one-half miles from Washington, D.C.'s western boundary, making Bethesda a close-in suburb of the nation's capital. Other focal points of downtown Bethesda include the Woodmont Triangle, bordered by Old Georgetown Road (Maryland Route 187), Woodmont and Rugby Avenues, and the Bethesda Row, centered at the intersection of Woodmont Avenue and Bethesda Avenue. Much of the dense construction in that area followed the opening of the Bethesda station on the Red Line of the Washington Metro rapid transit system, also located at this intersection and the centerpiece of the Bethesda Metro Center development. The Medical Center Metro stop lies about 0.7 miles north of the Bethesda stop, Medical Center, which serves the NIH Campus, the Walter Reed National Military Medical Center, and the Uniformed Services University of the Health Sciences.
