Major restoration in Minneapolis aims to renew ‘every square inch’ of country’s oldest basilica
The Basilica of Saint Mary in Minneapolis, the first U.S. basilica, is undergoing a major restoration begun in 2025 to preserve its 1915 structure and 20th‑century artwork. Restoration work includes specialized cleaning of marble apostle statues, masonry and roof repairs, pew refurbishment, and plaster restoration under the “Restoring Beauty, Inspiring Hope” campaign. The project aims to raise about $50 million and uses techniques like spraying a conservation material that dries into a latex‑like layer to protect the original finish. The basilica’s history dates to 1868, with the current Beaux‑Arts building completed in 1915, and the restoration seeks to renew every square inch of the historic edifice.

The Basilica of Saint Mary in downtown Minneapolis, the nation’s oldest minor basilica, is undergoing an extensive restoration that began in 2025 and is slated for completion by Palm Sunday 2027. The project, titled “Restoring Beauty, Inspiring Hope,” aims to repair, clean, and preserve every element of the historic structure, from its marble statues to its limestone façade, while also creating a preservation manual for future generations. 1 2
The basilica’s origins trace to a modest “shed church” built in 1868, followed by a larger Gothic‑Revival building before the current Beaux‑Arts edifice was erected. Construction began with the cornerstone laid in 1908; the first Mass was celebrated in 1914 and the church was dedicated in 1915. Pope Pius XI elevated the pro‑cathedral to a minor basilica in 1926, making it the first such designation in the United States. 1
The “Restoring Beauty, Inspiring Hope” campaign seeks roughly $50 million, drawing on parishioner donations and broader community support. The effort builds on restoration initiatives from the 1950s and ongoing work in the 1980s‑1990s, reflecting a long‑term commitment to the basilica’s preservation. 1
Restoration work officially began in 2025 after a master plan was launched in 2019 and delayed by the COVID‑19 pandemic. As of mid‑2026, scaffolding surrounds the nave, and major tasks such as limestone cleaning, pew restoration, and ceiling replastering are underway. Masses are temporarily held in the undercroft while the main worship space is being renovated. The project is progressing on an accelerated schedule, with weekly updates marking the countdown to the anticipated completion date. 2
Beyond completing the physical restoration, the project will produce a detailed preservation manual to guide future maintenance and minimize the need for large‑scale interventions. The basilica will continue to serve as a vibrant parish and a historic landmark, embodying both liturgical and architectural heritage for generations to come. 1*
Examine the Catholic Church’s preservation of historic basilicas

The Catholic Church preserves historic basilicas not merely as “old buildings,” but as living ecclesial goods: places where divine worship, evangelization, catechesis, and the Church’s cultural memory meet. This preservation is grounded in the Church’s conviction that sacred art and architecture belong to her ministry, and it is carried out through pastoral responsibility, formation of clergy, and careful stewardship aimed at safeguarding heritage from neglect, misuse, and exploitation.
The Church has “traditionally perceived” the promotion, custody, and valorization of the highest expressions of the human spirit in the artistic and historic fields as integral to her ministry. In this vision, the Gospel is announced and the divine cult is “perfected… with the aid of literary and figurative arts, music, architecture,” together with the conservation of “historic memories and precious documents” of the faithful. Historic basilicas therefore function as more than heritage sites; they are instruments of worship and communication of salvation.
A key argument in the Church’s reflection on cultural patrimony is that adequate conservation protects a heritage from being reduced to economic or technological uses alone. The Church emphasizes that protecting and valuing these goods helps humanity resist “dispersion” and “instrumentalization” and supports the “meaning and value of human life.”
The 1992 circular letter on the artistic and historic heritage stresses that the responsibility for cultural goods falls “particularly on the shoulders of the clergy,” under the guidance of bishops and the Successor of Peter. Clergy must preside over evangelization that also includes “the promotion, care and use of cultural goods,” and they are assigned the “wise and enlightened work of conservation” of community goods, including testimonies of previous generations’ faith.
The same document calls for seminary and houses of study to delineate and intensify programs on the artistic and historic heritage, so future priests develop understanding of the “complex juridical, liturgical, aesthetic, pastoral and technical issue of conservation, restoration, management, and responsibility” toward ecclesial cultural goods.
This matters for basilicas because the Church does not treat preservation as a specialist hobby outsourced to others; it is tied to pastoral leadership, particularly where the building is inseparable from liturgical use.
The 2018 guidelines on decommissioning and ecclesial management of former churches describe how religious heritage has “vitality” expressed in both material and immaterial ways. Spaces for worship inevitably transform as rites change, and there can be conflict between material conservation and liturgical function. The Church recognizes real risks such as closure due to changes in practice, political conflict, natural disasters, or even tourism pressures.
Crucially, the guidelines emphasize co-responsibility: the care of living religious heritage is “primarily the responsibility of the religious community,” ideally initiated by that community and carried out in collaboration with conservation professionals and other concerned parties.
The Church also addresses misconduct and neglect around sacred goods. The 1992 circular warns of “improper use” of artistic and historic collections—being removed for private use or collections, sometimes by arbitrary action and sometimes due to theft—and insists that priests themselves must assume responsibility for caring for these goods while protecting them.
This is highly relevant to basilicas: preservation is not only restoration after damage; it includes preventing unauthorized alteration, dispersal, or privatization.
A 2023 Acta Apostolicae Sedis text (centenary commemoration of a permanent commission) indicates that the Holy See sought “unità e continuità di indirizzo” in works of conservation and restoration of monuments dependent on the Holy See, along with more rational distribution of responsibilities. It frames the institution of commissions as an expression of ongoing concern for care and conservation of cultural goods.
Pope John Paul II, speaking to the Pontifical Commission for Sacred Archaeology, explicitly ties restoration efforts (such as preparing catacombs for public access) to “pastoral benefits,” because visits accompanied by educational and spiritual explanations become “a very effective form of catechesis” that inspires reflection on the Gospel message—part of the Church’s “new evangelization.”
While catacombs are not basilicas, the principle directly supports why the Church cares for historic sacred spaces: heritage is meant to serve evangelization, not only commemoration.
Even when physical structures suffer major vicissitudes—fire, enclosure changes, or later “restorations”—Catholic sources show a pattern: preservation often involves rebuilding to retain essential form and then gradually respecting or reinterpreting earlier identity.
A Catholic Encyclopedia article on Saint John Lateran describes how damage led to rebuilding (it was burnt down multiple times), yet the basilica “retained its ancient form,” with columns dividing aisles and an atrium with colonnades and fountain. It also notes later changes (including a seventeenth-century restoration) that altered the appearance, illustrating that preservation can be contested across eras.
This example is instructive: it shows that the Church’s approach to historic sacred architecture is not static. There is a recurring effort to maintain continuity of sacred identity even amid necessary reconstruction, though later historical taste can introduce changes that modern preservation debates evaluate differently.
The Encyclopedia’s entry on the Abbey of Grottaferrata notes that restoration efforts (e.g., a restoration by order of Leo XIII in 1881, and a “judicious but partial restoration” in 1904) included discovery and presentation of earlier artistic remains, such as fresco fragments.
This illustrates a preservation principle consistent with Catholic reflections on conservation: restoration can aim at revealing and protecting historical layers rather than replacing everything with a uniform “new look.”
From these sources, the Catholic preservation of historic basilicas can be summarized as a coherent model:
The Catholic Church preserves historic basilicas because she sees them as sacred places whose art, history, and architecture belong to her evangelizing and liturgical life. Preservation is therefore a matter of pastoral custody—rooted in the duty of clergy, supported by appropriate formation, and implemented with care for the building’s “living” function as a worship space, not merely as a cultural artifact.
