Built in 1884 to a design by Charles Coolidge Haight, it is a prominent regional example of Gothic Revival architecture.

Its main entrances are on the long south side, the eastern one set facing east in a projecting brick vestibule, and the western one sheltered by a wooden porch.

The vestibule extends further to a square three-stage tower, which is topped by an octagonal steeple and cross.

The building has undergone only modest external changes since its construction, the most notable being the 1957 enlargement of the organ wing on the north side to accommodate an organ the school had acquired from the Castle in the Clouds estate.
