The land that is now Kenmore Square was originally the swampy, uninhabited corner of the mainland, which marked where the narrow Charles River fed into the wide, marshy Back Bay. It was part of the colonial settlement of Boston until 1705, when the hamlet of Muddy River incorporated as the independent town of Brookline. The land ended up in Brookline because the Muddy River - several blocks to the east - formed the eastern border of the new city. Known as Sewell's Point at the time, an 1821 map shows the Great Dam, Brighton Road, and Punch Bowl Road intersecting at Kenmore which was now connected to the mainland to the west, in addition to the southern connection shown in 1777. The portion of Beacon Street west of Kenmore Square was laid out in 1850, intersecting with Avenue Street, Mill Dam Road, and Western Avenue, a road traversing the Back Bay mill dam in approximately the modern location of Beacon Street. The Boston and Worcester Rail Road and the Charles River Branch Railroad combined here to cross the Back Bay on a separate railroad bridge, making a beeline for the Leather District. The railroad lines still exist on more or less their original alignments, with the city developing around them. Minor adjustments have been made for the construction of South Station, what is now the MBTA Green Line, and the Massachusetts Turnpike. The city of Brighton was merged with Boston in 1874, and the Boston-Brookline line was redrawn to connect the new Back Bay neighborhood with Allston-Brighton. Even as late as 1880, Kenmore Square was only sparsely developed. By 1890, the Back Bay landfill project had reached Kenmore Square, for the first time fully connecting it with parts of the city to the east. Streetcar tracks were laid on Beacon Street in 1888, passing through Kenmore Square on the surface, from Coolidge Corner to Massachusetts Avenue. These would eventually become the Green Line C branch. Tracks were laid on what by then was called Commonwealth Avenue in 1896, from Union Square in Brighton. These would later serve the Green Line A branch and Green Line B branch. The Boylston Street subway was extended to Kenmore Square in 1914, where it rose above ground. In 1932, the Kenmore Square portion of the Green Line was put underground, and branch portals opened at Blandford and St. Mary's Streets. In 1915, the Kenmore Apartments were built on the corner of Kenmore and Commonwealth Avenue. Later, the apartments became the Hotel Kenmore with 400 guest rooms. The Kenmore was owned by Bertram Druker, a prominent Boston developer and was known as the baseball hotel. It housed every one of the 14 teams after World War II. From the 1960s to 1979 it was used by Grahm Junior College as a residence hall, cafeteria, library, and classroom facility. Later, after Grahm Junior College closed and larger hotels like the Sheraton were built, the Hotel Kenmore started to show its age and eventually became apartments again. It is now called Kenmore Abbey.
