The church features two towers and a tiled dome roof; it is both the tallest and most prominent landmark in Beaverville.

[2] The church's main entrance is located on its west side; the three sets of double doors are each topped by a stained glass transom.

A small flat octagonal section at the top of the dome is fenced off by an iron railing.

Due to the parish's increasing congregation, construction began on the current church building in 1909.
