Lehigh University has many buildings, old and new, on its three campuses. When the university was founded in 1865, it took over several buildings from the surrounding property. One which remains today is Christmas Hall, now part of Christmas-Saucon Hall.
The original campus contains most of Lehigh's academic and residential buildings and sits on the north slope of South Mountain overlooking Bethlehem's Southside. It has expanded many times during Lehigh's history as surrounding land has been purchased and as existing buildings around the campus have been acquired and converted. During recent years, intense work has been done on this campus. This has included the construction, expansion, or renovation of several buildings and significant improvements in traffic flow and pedestrian areas. Notable among the latter is the New Street corridor/Campus Square north entrance.
The Alumni Memorial Building is a Gothic building near the center of campus, housing the Visitor Center, the Office of Admissions, the Alumni Association, as well as the Office of the President. The building is a memorial to the 1,921 Lehigh alumni who served in World War I and the 46 who died. Plaques commemorating those who served in subsequent wars are situated in the lobby. The graceful building was meticulously conceived and designed by Lehigh alumni Theodore G. Visscher and James Lindsey Burley as an "architecturally unique memorial", as Mr. Yates notes. It took five years to complete.
Brodhead is an air-conditioned six-story high-rise building with an elevator. These four-person suites house 194 second-year students and students living in two themes of the Upper Class Experience Residential Communities. Each suite has two double bedrooms or one double and two single bedrooms, and all suites have a furnished common area and a private bathroom.
A relatively new complex of buildings on the northern edge, Campus Square consists of apartment style undergraduate housing, the university bookstore, retail space, and a parking garage. Its architecture reflects some changing attitudes towards southside Bethlehem by breaking the tradition of creating a visual wall between the campus and city. Instead, a plaza of buildings now opens out to the city along the New Street corridor/4th street, and directly into town.
