the campus, also on North Charles Street, there is the Evergreen House, former mansion home of the B&O Railroad's Garrett Family and now one of JHU's house museums, just past East Cold Spring Lane and the neighboring former Loyola College, now Loyola University Maryland. The majority of buildings on the portion of North Charles Street that borders Homewood are owned and operated by the university and are informally part of the Homewood Campus. Architecture The architectural style of the campus follows the Federal style of Homewood House. Most newer buildings resemble this style, being built of red brick with white marble trim. Homewood House was later used for administrative offices but now is preserved as a museum. The space is organized in quads around Gilman Hall. In 1997, the university purchased the vacant former building of the old all-girls Eastern High School (founded 1844, building constructed 1938). Old EHS is a three-story high 'H'-shaped building of red brick and limestone trim in English Tudor revival architecture, on East 33rd St., one mile (1.6 km) east of the "Homewood" campus. It is immediately across the street from the former site of the old Memorial Stadium of 1950, where the Major League baseball Baltimore Orioles and the NFL pro football's Baltimore Colts used to play. The former Eastern High building with its antique interior features was reopened in 2001, largely renovated and reconstructed, occupied by administrative offices for the Johns Hopkins Medical Institutions. The university undertook a major renovation of the Homewood Campus in 2000-2002. Asphalt, vehicle-accessible roads throughout the campus were replaced with brick-paved walkways. The traffic circle located in front of the Milton S. Eisenhower Library, facing North Charles Street, which for many years had existed as a half circle that connected to campus roads, was completed, in line with the original Master Plan for the university. Traffic was redirected to the periphery of the campus and greenery was added throughout the campus, with the goal of making the core areas of Homewood safer, more pedestrian-friendly and more attractive. A number of new buildings, including Clark Hall (home to the Biomedical Engineering department), Hodson Hall (a multi-use classroom building), the Mattin Center (a student arts and activities center), the Ralph S. O'Connor Recreation Center, and the New Chemistry Building, were also constructed in the early 2000s (decade). A second campus expansion, called Charles Commons, was completed in September 2006. It
