Hyllestad: The Lost Quarry Where Norway’s Medieval Stone Crosses Were Carved
Archaeologist Irene Baug was digging into a centuries-old waste heap at a millstone quarry in Hyllestad, western Norway, hoping for nothing more exciting than a clearer date range for when the site was worked. Then a stone cross turned up. Then another. Then another — seven in total, the discarded fragments of a craft historians knew existed but had never actually located the workshop for.
The find, at a glance
- Site: Hyllestad, Sogn og Fjordane, western Norway — a Viking-Age and medieval quernstone-quarrying landscape of roughly 400 individual quarries
- Found: seven fragments of carved medieval stone crosses, discarded in a quarry spoil heap; the largest surviving piece is 1.2 metres long, with the complete crosses estimated at 2–3 metres tall
- Led by: archaeologist Irene Baug, University of Bergen
- Dating: charcoal from the waste heap places quarry activity between the 11th and 13th centuries, with even earlier stone extraction beneath it
- Why it matters: this is the first time archaeologists have located the actual production site for Hyllestad’s stone crosses, not just the finished crosses themselves
A Quarry That Outlasted the Viking Age by 900 Years
Hyllestad’s quarries are not a single site but an entire industrial landscape — production of hand querns started here around 950 CE, during the Viking Age, and continued in some form until 1930. The local rock, a garnet mica schist, split cleanly and held an edge well, which turned Hyllestad into one of the most important quernstone and millstone sources in the North Atlantic; finished stones traveled from here to Denmark, Sweden, northern Germany, and Norway’s own Atlantic settlements, with Bergen acting as the trading hub. Sometime in the 11th century, as Norway’s conversion to Christianity took hold, the same quarrymen who split hand querns for grinding flour began carving something new: memorial and boundary stone crosses.
“We Were Absolutely Ecstatic”
Researchers already knew Hyllestad-style stone crosses existed — a handful survive in churches and museum collections across western Norway, forming what Baug calls a genuinely distinctive regional cross tradition found nowhere else in the country. What nobody had found before was where they were actually made. “We were absolutely ecstatic,” Baug has said of uncovering the fragments. “For us, finding the production site itself was an enormous breakthrough.” The crosses in the spoil heap were rejects — broken or flawed during carving and tossed aside with the ordinary quarrying debris, which is exactly why they survived undisturbed for roughly a thousand years.

Symbols of a New Faith, Carved by Old Hands
Norway’s conversion to Christianity is traditionally tied to kings like Olaf Tryggvason and Olaf Haraldsson (St. Olaf), but the groundwork was laid earlier, including under Haakon the Good in the 10th century. Baug’s research suggests stone crosses like Hyllestad’s were not something ordinary people simply purchased at a market — they were likely made to order, and it’s plausible that kings or powerful chieftains commissioned some of them directly. “They were probably powerful public symbols of the new faith,” Baug says, raised in the landscape as visible, permanent markers of a religious and political shift that was still being contested. That a Christian symbol was carved by craftsmen whose fathers and grandfathers had spent generations shaping tools for an entirely different economy is a small, concrete picture of how the Viking Age actually ended — not in a single battle, but in workshops like this one, tool by tool.
Why the Waste Heap Was the Real Discovery
It’s a quirk of archaeology that the most informative finds are often the ones that were thrown away. A finished stone cross tells you what the object looked like; a broken one, discarded mid-production, tells you how it was made, by whom, and roughly when — which is exactly what let Baug’s team narrow the quarry’s active period to the 11th–13th centuries using charcoal dating, while also confirming that stone extraction at the site began even earlier. The seven Hyllestad fragments are now one of the only known assemblages that ties a specific medieval stone-cross tradition directly to its own workshop floor.
Quick Answers
What did archaeologists find at Hyllestad? Seven fragments of carved medieval stone crosses, discarded as production waste in a quarry spoil heap in Hyllestad, western Norway.
How old are the stone crosses? Charcoal dating places the quarry’s cross-carving activity between the 11th and 13th centuries, within Norway’s Christianization period.
Why is this discovery significant? It’s the first time archaeologists have located the actual workshop where Hyllestad’s distinctive stone crosses were carved, rather than just finding finished crosses elsewhere.
What was Hyllestad used for before the crosses? It was one of the North Atlantic’s major quernstone and millstone quarrying centers, in continuous use from around 950 CE (the Viking Age) until 1930.
