St. Aloysius Church

St. Aloysius Church is a Renaissance-style building of worship in Washington, D.C., with a main altar featuring artwork by a significant American artist. The structure displays classical proportions and careful attention to architectural detail throughout its interior and exterior.

The church was built in 1859 and quickly became important to its community. During the Civil War, parishioners demonstrated their commitment by rapidly establishing a nearby support facility.

It served as a spiritual center for Irish Catholics in the neighborhood and continues to shape the character of the area today. The strong religious tradition remains visible in the architecture and artistic details that visitors can observe.

The church is located in an accessible area with public transit and parking nearby. Visitors should expect some uneven ground surfaces and note that the building may occasionally close for private events.

The architect who designed it also taught mathematics at a prominent university in the city during construction. His dual role as educator and designer reflects the intellectual diversity of the era.
