A projecting vestibule has a lower roof line than the main block, with a fully pedimented gable end, and the main entrance in a recess flanked by pilasters and topped by an entablature.

At the front of the main roof a two-stage tower rises, square in the first stage, and with an open octagonal cupola above.

[4] Castleton Medical College was founded in 1818, and this building was constructed in 1821.

It is believed to be the oldest surviving medical school building in the United States.

It was moved a short distance (200 yards (180 m)) in the 20th century to make way for new construction on the Castleton University campus.
