After the Great Boston fire of 1872, workers used building rubble as landfill along the downtown waterfront. During the mid-to-late 19th century, workers filled almost of brackish Charles River marshlands west of Boston Common with gravel brought by rail from the hills of Needham Heights. The city annexed the adjacent towns of South Boston (1804), East Boston (1836), Roxbury (1868), Dorchester (including present-day Mattapan and a portion of South Boston) (1870), Brighton (including present-day Allston) (1874), West Roxbury (including present-day Jamaica Plain and Roslindale) (1874), Charlestown (1874), and Hyde Park (1912). Other proposals were unsuccessful for the annexation of Brookline, Cambridge, and Chelsea. Boston went into decline by the early to mid-20th century, as factories became old and obsolete and businesses moved out of the region for cheaper labor elsewhere. Boston responded by initiating various urban renewal projects, under the direction of the Boston Redevelopment Authority (BRA) established in 1957. In 1958, BRA initiated a project to "improve" the historic West End neighborhood. Extensive demolition was met with strong public opposition, and thousands of families were displaced. The BRA continued implementing eminent domain projects, including the clearance of the vibrant Scollay Square area for construction of the bleak, modernist style Government Center. In 1965, the Columbia Point Health Center opened in the Dorchester neighborhood, the first Community Health Center in the United States. It mostly served the massive Columbia Point public housing complex adjoining it, which was built in 1953. The health center is still in operation and was rededicated in 1990 as the Geiger-Gibson Community Health Center. The Columbia Point complex itself was redeveloped and revitalized from 1984 to 1990 into a mixed-income residential development called Harbor Point Apartments. By the 1970s, the city's economy had begun to recover after 30 years of economic downturn. A large number of high-rises were constructed in the Financial District and in Boston's Back Bay during this period. This boom continued into the mid-1980s and resumed after a few pauses. Hospitals such as Massachusetts General Hospital, Beth Israel Deaconess Medical Center, and Brigham and Women's Hospital lead the nation in medical innovation and patient care. Schools such as the Boston Architectural College, Boston College, Boston University, the Harvard Medical School, Tufts University School of Medicine, Northeastern University, Massachusetts College of Art and Design, Wentworth Institute of Technology, Berklee College of Music, the Boston Conservatory, and many others attract students to the area.
