In 1920, a foundation stone of great importance was placed in Washington, D.C. That stone is the cornerstone of America’s Catholic Church, the Basilica of the National Shrine of the Immaculate Conception, our nation’s preeminent Marian shrine and patronal church.

Now, as its one hundredth anniversary approaches, Mary’s Shrine, as the Basilica is also known, is prepared to receive its crowning jewel with the mosaic ornamentation of its great dome, the Trinity Dome.

Throughout the construction process, we will post behind-the-scenes images, video, historical commentary, and detailed updates on the Trinity Dome project. Thank you for joining us on this journey!
