Kensington, Maryland  Kensington is a town in Montgomery County, Maryland, United States. The population was 2,213 at the 2010 United States Census. Greater Kensington encompasses the entire 20895 ZIP code, with a population of 19,054. The area around the Rock Creek basin where Kensington is located was primarily agricultural until 1873, when the B&O Railroad completed the Metropolitan Branch which traversed Montgomery County. A community arose where the new railroad line intersected the old Rockville-to-Bladensburg road. This early settlement was first known as Knowles Station. In the early 1890s, Washington, D.C. developer Brainard Warner began purchasing land parcels to build a planned Victorian community, complete with church, library and a local newspaper. Fascinated by a recent trip to London, Warner named his subdivision Kensington Park, the 10th and largest subdivision in the area which became the Town of Kensington. Upon incorporation in 1894, Warner convinced the Mayor and Council to name the town Kensington. The historic core of Kensington was listed on the National Register of Historic Places, as the Kensington Historic District in 1980. Originally a farming community at Knowles Station, Kensington developed into a summer refuge for Washington, D.C., residents wishing to escape the capital's humid summers. As years passed and its residents increasingly remained year round, Kensington evolved into a commuter suburb. The large southernmost section originally mapped out by Warner remains largely unchanged since inception, and is a historically preserved zone. Indeed, the only major changes in the town's basic layout have been the bridging over of the original railroad crossing in 1937, and the extension and widening of Connecticut Avenue, the town's main thoroughfare, in 1957. In March 1975, Kensington gained attention regionally due to the disappearance of Sheila and Katherine Lyon. The sisters walked to Wheaton Plaza, a local shopping mall where they were seen by witnesses including their brother. However, they never returned home. The case was not resolved until 2017. The town gained national attention three times in a 10-month span early in the 21st century as a result of events which occurred within a mere quarter-mile radius. In December 2001, the town responded to complaints from anonymous citizens by banning Santa Claus from the annual holiday parade. Protesters arrived at the parade en masse, including dozens of Santas riding everything from motorcycles to fire trucks. Eight months later, an Amtrak train derailed adjacent to the town center when the tracks separated at an overheated joint, injuring 72 people, though there were no fatalities.
