[1] The South Stone School House is located in the center of the southern part of the island, at the southeast corner of Main Street and Quarry Road.

It is a single-story structure, built out of locally quarried limestone that is known in the trade as "black marble".

The gabled roof is framed with wooden timbers, and a wide stone chimney rises from one of the long sides, just to the left of the doorway.

The interior has a single large chamber, finished with pine wainscoting and plaster on the walls.
