Basilica of the National Shrine of the Immaculate Conception

Although the basilica is situated within the geographical boundaries of the Archdiocese of Washington, the basilica is not a parish of the archdiocese, does not have its own parish community, and the shrine's administration does not fall under the direct authority of the local Archbishop, but it serves adjacent Catholic University, which donated the land for its construction, and the United States Conference of Catholic Bishops. It also hosts numerous Masses for various organizations of the Church from across the United States. The basilica is not the cathedral of the archdiocese, as that title and honor belongs to the Cathedral of St. Matthew the Apostle, although numerous archdiocesan events are held at the basilica. As of 2025, the rector of the basilica is the Reverend Monsignor Walter R. Rossi, who holds a Licentiate of Canon Law. The basilica is served by the Brookland–CUA station on the Red Line, roughly away. ==Architecture==

The basilica houses 82 Marian chapels (including the Our Mother of Africa Chapel), as well as other sacred images, flanking the sides of the Great Upper Church and the Crypt Church. They were designed to reflect the origins of Catholic Americans and the religious orders whose generosity erected them. Its Greek-styled interior is crowned with numerous domes decorated in mosaics, similar to the Basilica of St. Mark in Venice, Italy, but much larger. The mosaics feature American renditions of traditional Catholic images. Artist Jan Henryk De Rosen, who presided over the shrine's iconography committee was also responsible for much of its decor, including composing the large mosaic over the northern apse. The basilica is dedicated to the Immaculate Conception, the United States' principal patroness. The Trinity Dome (the main dome of the structure) is only smaller than that of the U.S. Capitol. The interior area of the basilica is for the Upper Level and Great Upper Church, and for the Lower Level and Crypt Church, for a grand total of . The shrine was built in the style of medieval churches, relying on thick masonry walls and columns in place of structural steel and reinforced concrete. It was designed to hold 10,000 worshipers and includes modern amenities such as a basement cafeteria, hidden public address speakers to carry speech at the altar to the rear of the building, air conditioning and what was the largest radiant heating slab in the world (in 1959). There are arches outlined with iridescent Pewabic Pottery tile, large ceramic medallions set in the ceiling, and fourteen Stations of the Cross in the Crypt Church. ==History==

Patronage of the Immaculate Conception In 1792 John Carroll, the bishop of Baltimore and the United States's first Catholic bishop, consecrated the newly created United States under the protection of the Blessed Virgin Mary under the title of the Immaculate Conception. In 1846, the 6th Provincial Councils of Baltimore reiterated this episcopal choice to name the title Virgin Mary, conceived without sin as the principal patroness of the land. Pope Pius IX formalized the decision on February 7, 1847, and it was published on July 2, 1847. Construction (20th century) , founder of the Shrine Bishop Thomas Joseph Shahan, the fourth rector of the Catholic University of America in Washington, D.C., proposed the construction of a national shrine to commemorate the Immaculate Conception in the country's capital. Bishop Shahan took his appeal to Pope Pius X on August 15, 1913. Shahan received the pope's enthusiastic support and personal contribution of US$400 (US$11,681 in 2022, adjusted for inflation). Shahan returned to the United States and persuaded the board of trustees of The Catholic University of America to donate land at the southwest corner of the campus for his shrine. In January 1914, Shahan published the first issue of Salve Regina, a newsletter meant to stir enthusiasm for his project. He wrote that the shrine would be a "monument of love and gratitude, a great hymn in stone as perfect as the art of man can make it and as holy as the intentions of its builders could wish it to be." His newsletter was circulated to dioceses throughout the country and financial donations began to pour into Washington. In 1915, Shahan appointed Father Bernard McKenna of Philadelphia as first director of the national shrine. Shahan oversaw the construction of the shrine until his death on March 9, 1932. His are the only remains interred at the basilica. By 1919, Shahan and McKenna chose architectural drawings by the Boston firm of Maginnis & Walsh for construction of the national shrine. Initially, they considered a traditional Neo-Gothic architectural style, but Shahan opted instead for a Byzantine Revival–Romanesque Revival design. On May 16, 1920, Archbishop Giovanni Bonzano, Apostolic Nuncio to the United States of America, celebrated Mass and blessed the site of the future National Shrine. On September 23, 1920, Cardinal James Gibbons, archbishop of Baltimore, blessed the foundation stone. More than 10,000 people attended the Mass, including ambassadors, government officials, and military officers. On April 20, 1924, the first public Mass ever offered at the shrine was held in the unfinished Crypt Church. In 1932, the death of Bishop Shahan and the Great Depression halted the construction above the completed Crypt Church level. The beginning of American involvement in World War II stalled plans even further, and construction was not resumed until 1954. After the war, in 1953, American bishops under the leadership of John Noll, archbishop ad personam of Fort Wayne, and Patrick O'Boyle, archbishop of Washington, pledged to raise the funds necessary to complete the Great Upper Church of the national shrine. On November 15, 1954, work was resumed on building the shrine, and on November 20, 1959, thousands of Catholics gathered with the bishops for the dedication of the Great Upper Church. Since 1968, the Papal Tiara of Pope Paul VI has been on display inside the Crypt Church. On October 12, 1990, Pope John Paul II raised the national shrine to the status of a minor basilica. The papal bull was signed and notarized by Cardinal Agostino Casaroli. It is the 36th designated basilica within the United States. ==Completion (21st century)==

In August 2006, work was completed on a mosaic covering the Redemption Dome in the Great Upper Church. Following its completion in the summer of 2007, the Incarnation Dome was blessed on November 17, 2007. A small chapel on the Crypt Church level honoring Our Lady of La Vang (Vietnam) was completed in 2006. In 2008, during his trip to the United States, Pope Benedict XVI bestowed the Golden Rose upon the Basilica of the National Shrine of the Immaculate Conception. In June 2011, a new chapel dedicated to Our Lady of Lebanon was erected within the basilica, commemorating the fidelity of the Maronite Church and its faithful. A mosaic of Saint Maroun and the Crucifixion was copied from the 6th-century Rabbula Gospels manuscript, and was donated by Cardinal Donald Wuerl. The chapel was formally consecrated by Maronite Bishop Gregory J. Mansour on September 23, 2011. On January 26, 2013, the basilica held a televised thanksgiving Mass and enshrined two first class relics of Americans Kateri Tekakwitha and Marianne Cope, who were both canonized October 20, 2012. Pope Francis visited the shrine on September 23, 2015, and celebrated a Mass for the canonization of Saint Junípero Serra, O.F.M., on the mall of the Catholic University of America. The altar, ambo, and chair used for this Mass match the existing marble in the basilica. After the Mass, the papal altar was placed in front of the High Altar, and is now used as the altar in the Great Upper Church. On February 20, 2016, the basilica was the site of the funeral Mass of US Supreme Court Justice Antonin Scalia at which his son Fr. Paul Scalia was the celebrant. The final architectural element was completed with the installation of the 24 tons of Venetian glass in the central Trinity Dome, one of the largest mosaics of its kind in the world. On December 8, 2017, the Feast of the Immaculate Conception, the dome was dedicated and solemnly blessed by Cardinal Donald Wuerl. ==Priests of the Basilica==
