A Metal Detectorist In Switzerland Just Found A Nine-Inch Bronze Axe That Dates Back 3,500 Years

Published March 27, 2026

Sacha Schneider was using a metal detector to survey the steep slopes that overlook the village of Burg im Leimental when he discovered this nine-inch bronze relic that dates back to the Bronze Age.

While walking through the dense woods near Burg im Leimental, Switzerland, a volunteer surveyor recently came across a bronze axe. This astonishing relic is believed to be some 3,500 years old — and archaeologists suspect that it may have been some kind of ceremonial offering to an unknown deity.

Indeed, this bronze axe is not the only Bronze Age object that’s been found in the area over the past 100 years. Archaeologists are still trying to figure out whether the axe was a standalone offering or possibly part of a larger treasure hoard.

The Bronze Age Axe Found By A Volunteer Archaeologist In Switzerland

According to a statement from Archaeology Baselland, the bronze axe was discovered by Sacha Schneider, a volunteer surveyor, in the Swiss village of Burg im Leimental, in 2024. Schneider had taken his metal detector onto the castle rock, a steep, wooded slope beneath Biederthal Castle. While searching the slope, Schneider found the bronze axe as well as a dress pin.

The bronze axe is “massive” at almost nine inches long, and it belongs to the flanged variety, characterized by its raised sides. It’s more specifically known as a “Grenchen type” axe, named after the discovery of a large Bronze Age cache of axes, swords, and sickles that had previously been found in the nearby Swiss town of Grenchen in 1998.

Both it and the dress pin date back to the Middle Bronze Age, around 1500 B.C.E. And archaeologists suspect that they were buried on purpose. Indeed, it’s likely that these objects were left as an offering to a deity by Bronze Age people more than three millennia ago.

Other Bronze Age Objects Found In Burg im Leimental — And What Their Purpose May Have Been

As Archaeology Baselland noted in their statement, a number of other Bronze objects have been found in the region over the past two centuries. In the same area of castle rock where Schneider found the bronze axe and dress pin, a bronze sickle was also found in 1858. Archaeologists suspect that these may have been left by Bronze Age people, who sometimes buried bronze objects as offerings for unknown deities.

“The phenomenon of hoards — the deposition of multiple metal objects — was widespread in the Bronze Age,” the statement explains. “Sometimes, more than a hundred objects were deposited in a very small area. Often, various objects such as tools, weapons, and jewelry were found mixed together. Research assumes that such hoards were deliberately buried. In most cases, they are interpreted as votive offerings to unknown deities.”

The bronze axe was found in a “rocket pocket filled with earth,” and thus could have been a single offering instead of part of a hoard. Other such individual offerings have been found before, in rock crevices or even in the water. But because other bronze objects have been found in the area, archaeologists aren’t sure if the axe was an individual offering, or if it was part of a larger hoard that became spread out over the years, possibly due to looting.

Indeed, though Burg im Leimental is a “peripheral” place today, tucked along the border between Switzerland and France, it may have been more central during the Bronze Age. Not only is it situated in a fertile region, with connections to the Rhine and Rhone valleys, but other Bronze Age objects found in Grenchen in Switzerland and Biederthal in France suggest the presence of Bronze Age people in the region thousands of years ago.

While we know little about these people today, including which gods they may have worshipped, they did leave behind clues that hint at their mysterious history. Discoveries like the bronze axe offer fascinating insights into their craftsmanship, religious beliefs, and movements across the Bronze Age world.
