Basilica of the National Shrine of the Immaculate Conception, Washington D.C.

The Basilica of the National Shrine of the Immaculate Conception is a well-known Roman Catholic basilica in the Latin Rite tradition. It's dedicated to the Blessed Virgin Mary, particularly as Our Lady of the Immaculate Conception, who is the primary Patroness of the United States. This basilica is the largest Catholic church in the U.S., ranked 21st globally, and the tallest structure in Washington, D.C. It draws around one million pilgrims annually, from both the U.S. and abroad.

The construction of this impressive church, known for its Neo-Byzantine architectural style, commenced in 1920 under the supervision of John McShain, a contractor from Philadelphia. It was inaugurated but left incomplete in 1959.

Over the years, the basilica has received the honor of hosting several visits from popes, including Pope John Paul II, who designated it as a Minor Basilica on October 12, 1990, and Pope Benedict XVI, who presented the basilica with the Golden Rose. The Basilica primarily serves the nearby University, the United States Conference of Catholic Bishops, and hosts Holy Masses for Catholic organizations nationwide, without its own parish community.

Inside the Basilica, you'll find 70 chapels, each dedicated to honoring Mary and reflecting the diverse origins of Catholic immigrants and religious orders whose contributions made these chapels possible. The interior of the basilica is designed in a Greek style, adorned with numerous domes covered in mosaics. This mosaic work, inspired by Venice's Basilica of Saint Mark but on a grander scale, features Catholic imagery with an American touch. Artist Jan Henryk De Rosen decorated the basilica, including the prominent mosaic above the northern apse.

Why You Should Visit:
Just the sheer size and amount of work it had to take to build will amaze you, let alone how magnificent it looks.
