Rare medieval burial discovery in Turku

Archaeologists have uncovered around 100 intact medieval human remains beneath the floor of Turku Cathedral during renovation work, Yle reports.

The remains, dating from the 14th century to the mid-15th century, were found in the basement of the Ursula Chapel, completed in 1450. Archaeologist Kari Uotila described the preservation as exceptional, as such old remains are typically disturbed by later burials.

The bodies were likely interred directly beneath the walls when the chapel was built, with additional remains found outside the church walls. The floor had not been opened since 1450, leaving the burials undisturbed.

Among the remains are children, though fewer than in previous excavations at Turku’s St. Mary’s Church. Uotila noted that children’s bones rarely survive as long as those of adults.

No grave goods were found, as was customary in medieval burials. The deceased likely represented neither the wealthiest nor the poorest in society, Uotila said.

Plans include dental analysis to study diet and other aspects of their lives. The remains will later be reburied in a cemetery. Excavations are ongoing, with results expected in about a year.

The cathedral’s €24 million renovation began in spring 2026 and is set to finish by Advent 2028.
