The archaeological discovery, which was made over the span of two years, is something of a mystery. Archaeologists have uncovered the remains of at least 64 people, including men, women and children. But the bones come in all shapes and sizes, and dating them has proven a challenge.
The bones were gradually recovered between 2018 and 2020 during conservation works at St Nicholas Church in Gdansk, northern Poland.
The 12th-century church, one of the oldest in the city, was closed in October 2018 due to structural damage and the threat of collapse.
That same year, conservators stumbled upon the first batch of bones when working on the church's western and southern walls.
Just two years later, even more human remains were recovered.

Archaeologist Dr Aleksandra Pudło said: "We found mostly hand bones, spine elements, forearm bones and many more."
The bones most likely belonged to men, women and children aged 20 to 70.
And among them were the remains of at least six unborn children, which suggests heavily pregnant women were laid to rest under the church.
After analysing some 2,600 bones, Dr Pudło determined the archaeologists have uncovered the remains of 64 different people.
