Basilica of the Assumption, Baltimore

The Basilica of the Assumption, referred to as the Baltimore Basilica, is a Roman Catholic Church. It was the first Roman Catholic cathedral built in the United States and was among the first religious buildings constructed after the adoption of the U.S. Constitution. It was consecrated on May 31, 1821.

Construction on the Baltimore Basilica began in 1806. Architect Benjamin Henry Latrobe, known as "the Father of American Architecture," designed the building in the Neoclassical style with guidance from John Carroll, the first American bishop of the Roman Catholic church.

The cathedral is noted for its onion-shaped dome. The interior has many works of fine art, including two that were gifted to the basilica by King Louis XVIII of France.

The Basilica of the Assumption is on the U.S. National Register of Historic Places and is considered a U.S. National Historic Landmark.
