Built in 1752, Connecticut Hall is the oldest and only surviving building from the Old Brick Row on Yale?s campus under the direction of Thomas Clap, who was president of Yale at that time. Also known as Middle South, it was built 100 feet (30 m) long by 40 feet (12 m) wide, and three stories high and was then augmented to four stories. The design was Gregorian-style based from the Massachusetts Hall at the Harvard University.

Several restorations have been done to the Connecticut Hall. First was when it got demolished in the early 20th century and was saved by a group of alumni led by Professor Henry Farnam. It also got devastated after World War II but was rebuilt by Douglas Orr and Richard Kimball and soon after, the it was declared a National Historic Landmark in 1965.

Originally built as a student dormitory, Connecticut Hall now houses the offices of Yale?s Philosophy Department. On the second floor is the Faculty Room where the Faculty of Arts and Sciences organizes its meetings. Moreover, a computer cluster is located in the basement which is home to the group of students known as CTHallGremz, short for "Connecticut Hall Gremlins" who are generally students of Humanities.
