Dahlgren Chapel (1893) In contrast to most Catholic schools where the church is the dominant building on campus, Georgetown's chapel is modest by comparison. Situated directly west of the Healy Building, Dahlgren Chapel forms the crux of the original Quadrangle or "Yard" of the main campus. The building remains the center of Catholic liturgical activity on the campus, and is a popular site for weddings during the year. (Click on either photo to continue.)
