Cleveland Park was once considered so far away and distant from downtown D.C. that it was mainly known as a bucolic spot to build summer estates. But with the Rock Creek Railway line’s arrival in 1892, this formerly remote patch of land became accessible to commuters, and developers created a suburban-style idyll in D.C.’s Northwest quadrant. Much of Cleveland Park has curvilinear streets that follow the neighborhood’s natural contours instead of the rigid grid of most of D.C. This gentle road layout matches the peaceful atmosphere of the leafy streets and stately homes. Since its earliest days, Cleveland Park has attracted well-known architects, and one can find notable residences here in almost every style — with choices including Queen Anne Victorians, apartments in the historic Broadmoor, or an International Style house designed by I.M. Pei.
