Built in 1901 of yellow brick with terra cotta trim, it is cruciform in plan with two tall towers, a clerestory, and a dome.

[3] St. Augustine parish was founded in 1863 by German American residents of Lawrenceville, who had been operating a small school there for a few years.

St. Augustine was merged with three other Lawrenceville parishes—Holy Family, St. John the Baptist, and St. Mary's—to form the Parish of Our Lady of Angels.

Inspired by St. Benno's Church in Munich, it is an example of Romanesque Revival architecture with twin 148-foot (45 m) towers and a high dome.

The front of the church features three large arched doorways with decorative tympana under a niche containing a 12-foot (3.7 m) statue of St. Augustine.
