Medieval Origins and Construction

St. Mary’s Church was constructed at a strategic location outside the original city walls, close to the eastern bank of the Alna River in what is now Gamlebyen (Old Town). Construction began in the late 11th or early 12th century, reflecting Norway’s rapid Christianization and the city’s growing prominence (Visit Oslo). The original Romanesque stone basilica featured a simple nave and choir, with locally sourced stone and some imported materials highlighting the resources devoted to its construction.

By the 13th century, the church was significantly expanded. A choir and transepts were built, establishing a cruciform plan. The progression from wood to stone, and later to Gothic elements, parallels Oslo’s rise as a political and religious center (core.ac.uk).

Royal and Ecclesiastical Significance

St. Mary’s Church became Oslo’s royal chapel and seat of the influential collegiate chapter by the 14th century. It was intimately associated with the Norwegian monarchy: King Haakon V was crowned and buried here, and from 1314, the church’s provost served as Chancellor of Norway (archaeolist.com). Its proximity to the royal residence, Oslo Manor House, made it a center for both religious and state ceremonies.

The church’s role extended beyond worship, encompassing the administration of royal documents, education, charity, and the safekeeping of important relics. Its clergy influenced both religious and civic life in medieval Oslo (SpottingHistory).

Architectural Evolution and Archaeological Discoveries

The church underwent major transformations across three main building phases, evident in the different masonry styles found today. The 14th-century Gothic expansion introduced ribbed vaults, pointed arches, and large windows, while two imposing western towers gave the church a commanding presence (explanders.com). Excavations have revealed the foundations of ancillary chapels, sacristies, and burial vaults for Oslo’s medieval elite.

Archaeological digs led by Nicolay Nicolaysen, Gerhard Fischer, and Håkon Christie uncovered royal tombs, medieval gravestones, coins, ceramics, and religious artifacts (core.ac.uk). The discovery of King Haakon V and Queen Euphemia’s remains underscored the church’s royal significance, with their remains now reinterred at Akershus Castle (SpottingHistory).

Fragments of carved stonework and traces of color from wall paintings suggest the church was richly decorated, reflecting both Romanesque and Gothic artistic traditions (Norsk institutt for kulturminneforskning).

Decline, Ruin, and Rediscovery

The church’s fortunes waned following the Black Death, political upheaval, and especially the Protestant Reformation, which led to the dissolution of the collegiate chapter and transfer of its assets to the Crown. In 1523, Swedish forces set fire to the church, and a destructive fire in 1567 during the Northern Seven Years’ War left it in ruins (wikipedia). By 1542, the structure was demolished, and its stones repurposed for other buildings, including nearby Akershus Fortress.

Oslo’s urban core shifted after a fire in 1624, leaving the ruins buried until archaeological efforts in the 19th and 20th centuries brought them back to public attention.
