No visit to Washington, D.C.'s Georgetown neighborhood is complete without stopping by the oldest and largest Catholic and Jesuit university in the U.S. Founded in 1789 by Archbishop John Carroll, Georgetown University is a major international research university. Academically, the college is known for its law, medical, and international affairs programs, as well as its Edmund A. Walsh School of Foreign Service (the first of its kind in the country). Outside the classroom, the Corp—the largest student-run corporation in the country—and its basketball team have garnered national attention.
Whether you take a student or self-guided campus tour, definitely visit Healy Hall. A fusion of Romanesque, Gothic, and early Renaissance architectural styles, it was built between 1877 and 1879 and is named for the Rev. Patrick Healy, the first African-American to earn a Ph.D. and be president of a university (Georgetown, of course). Inside you'll find Gaston Hall, a 700-plus seat lecture hall that has hosted numerous world leaders.
