The Trinity Dome Galleries

The Trinity Dome is the central and largest dome of the basilica, which is the nation’s preeminent Marian shrine, dedicated to the patroness of the United States, the Blessed Virgin Mary under her title of the Immaculate Conception. The Trinity Dome mosaic will portray The Most Holy Trinity, the Blessed Virgin Mary, and a procession of saints, all of whom have an association with the United States and the National Shrine.

Nearly 100 years ago work began on the Shrine. Over the ensuing years, the basilica has embraced a stunning medley of artwork depicting the diversity of cultures and ethnicities represented throughout the United States. The finished mosaic will be the Crowning Jewel of the shrine, exemplifying these numerous cultures and diversity of people served at the basilica.
