One of the more historic buildings on campus, Pearson Hall was designed by architect Charles Bulfinch and built in 1817 as a chapel. It was one of three buildings, including Foxcroft and Bartlet halls, that made up Seminary Row. Together, the three buildings formed the heart of the Andover Theological Seminary, which at the time shared this area atop Andover Hill with Phillips Academy. The building was physically moved to its current location in the 1920s when the Andover campus underwent a major restructuring. Today, the building is home to Andover's classics department, its antique classrooms providing the perfect atmosphere for studying Latin and Greek. In 2014, the building also became home to the Tang Institute, a research center of sorts dedicated to exploring, supporting, and developing innovative approaches to teaching and learning.
