The 1891 Lockport Union High School was by far the largest and most sophisticated of all of Bethune & Bethune educational projects. The Richardson Romanesque Style two-story structure was built in brick with “brown” stone, possibly Medina sandstone, details.

The building’s main entrance was augmented by a stone arch, which was replicated at the other six entries. There are several defining features of this building, but the most significant is the bell tower. Four stories tall, the tower had massive windows with stone lintels and was capped by a crenulated open room for the bell and a hipped roof. A small round turret above it further augmented the tower. In the middle of the building, over the intersection of the main rectilinear building and the flanking wings, stood a square cupola.
