On November 6, 1789, Pope Pius VI issued a bull establishing the Diocese of Baltimore—the first Catholic diocese in the newly independent United States of America. At its head he placed John Carroll, a Jesuit priest who had helped draft the American Constitution's religious liberty clauses and whose cousin Charles had been the only Catholic to sign the Declaration of Independence. From this beginning in a city where Catholics had once been forbidden to worship publicly, American Catholicism would spread across a continent.
The story of Baltimore's Catholic preeminence begins in colonial Maryland, founded in 1634 as a haven for persecuted English Catholics. When religious tolerance fluctuated and penal laws were imposed, Maryland Catholics worshiped in secret or in private chapels on isolated farms. The American Revolution changed everything. Archbishop Carroll's Baltimore became the mother diocese for all of Catholic America—every bishop ordained in the 18th and early 19th centuries traced his authority back to this city.
Today, the Basilica of the National Shrine of the Assumption of the Blessed Virgin Mary stands as a monument to that founding era. Designed by Benjamin Henry Latrobe, architect of the U.S. Capitol, and completed in 1821, it was the first metropolitan cathedral built in the United States and remains one of the finest examples of neoclassical architecture in America. Steps away, Baltimore's Cathedral of Mary Our Queen serves as the working seat of the archdiocese. Together with the tomb of Cardinal James Gibbons and the historic parishes that served waves of German, Irish, Polish, and African American Catholics, Baltimore offers pilgrims a journey through the full arc of American Catholic history.
📜 History & Spiritual Significance
The Catholic presence in what is now Maryland dates to March 25, 1634, when English colonists landed at St. Clement's Island and Jesuit Father Andrew White celebrated what is believed to be the first Catholic Mass in the English-speaking colonies. The Maryland colony, founded by the Catholic Lord Baltimore (Cecil Calvert), was intended as a refuge for Catholics fleeing persecution in England.
The Maryland Toleration Act of 1649 guaranteed religious freedom, but this enlightened policy was overturned when Protestants gained control of the colony in 1692. For nearly a century, Catholics could not vote, hold office, or worship publicly. Masses were celebrated in secret, often in private homes. This persecution ended only with American independence.
John Carroll, born in Upper Marlboro, Maryland, in 1735, was educated at Jesuit colleges in Europe and ordained a priest in 1769. When the Jesuits were suppressed in 1773, he returned to Maryland and served Catholics on his family's estate. His cousin Charles Carroll of Carrollton became the only Catholic signer of the Declaration of Independence.
In 1789, Pope Pius VI appointed John Carroll the first Bishop of Baltimore—and thus the first Catholic bishop in the United States. The diocese originally encompassed the entire nation. Carroll established Georgetown College (1789), the first Catholic university in America, and St. Mary's Seminary (1791), the first seminary.
The cornerstone of the current basilica was laid on July 7, 1806, with Bishop Carroll presiding. Designed by Benjamin Henry Latrobe in the neoclassical style he would also employ for the U.S. Capitol, the basilica was completed in 1821—the year after Carroll's death. Pope Pius XI elevated it to the status of minor basilica in 1937.
The Baltimore Catechism, the standard Catholic religious education text for over a century, was produced by the Third Plenary Council of Baltimore held here in 1884. Cardinal James Gibbons, who served as Archbishop of Baltimore from 1877 to 1921, became the most prominent Catholic leader in America, advising presidents and championing workers' rights.

Basilica of the National Shrine of the Assumption of the Blessed Virgin Mary
America's first cathedral and a masterpiece of neoclassical architecture
The basilica is among the most architecturally significant churches in America. Latrobe's design features a double-shell dome that floods the interior with natural light, creating an atmosphere of transcendent beauty. The high altar was a gift from the parishioners of the Cathedral of Notre-Dame de Paris. The undercroft contains the tombs of Archbishop John Carroll, Cardinal James Gibbons, and other prelates who shaped American Catholicism.
Following an extensive restoration completed in 2006, the basilica shines as Latrobe intended. The interior evokes the Roman churches the architect studied, while the exterior speaks to the optimism of the early American republic.
