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 Rabboula Maronite 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 Walter R. RossiRector Vito A.
