# Divers Recover 10,500-Year-Old Worked Timbers From a German Lake Bed

*The finds beneath Lake Arendsee predate farming in Central Europe by 3,000 years and may be the remains of Mesolithic dwellings*

## In brief

- Worked wooden timbers about 10,500 years old were found 20 meters down in Lake Arendsee, Saxony-Anhalt
- The largest piece is a 1.6-meter post with felling marks; split planks measure up to 1.3 meters
- The site predates Central Europe’s first farming communities by about 3,000 years
- A sinking salt dome under the lake preserved the ancient shoreline under a thin layer of sediment
- Researchers are using sonar-equipped underwater vehicles to map the full extent of the site

Archaeologists in northern Germany have recovered wooden posts and planks cut and shaped by hunter-gatherers about 10,500 years ago, some of the oldest worked timber ever found in Europe, state heritage officials said on Wednesday.

The wood came up from the bed of Lake Arendsee in Saxony-Anhalt, where it lay preserved under sediment about 20 meters below the surface. The pieces include a post 1.6 meters long bearing felling and working marks and split planks measuring as much as 1.3 meters, [according to the State Office for Heritage Management and Archaeology Saxony-Anhalt](https://idw-online.de/en/news878279).

What the timbers were part of is the open question. The post may have been a supporting element in a structure, and the split boards point to deliberately built wooden architecture, but archaeologists have not yet found enough of the original arrangement to say whether the site held huts, a specialized installation or something they have not seen before from the period.

The answer matters because of the date. The site predates the first farming communities in Central Europe, and their longhouses, by roughly 3,000 years. Farmers reached the region around 5500 B.C., and they have long been treated as the people who first built permanent architecture and reshaped the land. Evidence that hunter-gatherers built substantial structures thousands of years earlier would complicate that account.

Wood almost never survives from the Mesolithic period. Stone tools and animal bones do, which means the record of how hunter-gatherers lived has been built mostly without the material they probably used most. In central Germany, Mesolithic buildings have previously been traced only through discolorations in the soil. Harald Meller, the state archaeologist of Saxony-Anhalt, said the preservation at Arendsee offers an unusually direct look at a material that normally vanishes.

The lake itself did the preserving. Arendsee sits above an underground salt dome, and geological processes have slowly made the lake bottom sink. As the floor descended, it carried the ancient shoreline down with it, leaving pieces of the Mesolithic landscape sealed beneath a thin layer of sediment rather than erased as the lake filled in. Traces of human activity that once lay at the water’s edge now sit about 20 meters down.

Archaeologists from the state office have worked at Arendsee for years, and earlier dives turned up Neolithic fish fences and medieval boats. The new finds reach far deeper into the past. At the time the timbers were cut, communities in Central Europe still lived by hunting, gathering and fishing. They clearly occupied the shores of the lake, but evidence of how they organized and built their living spaces has been scarce.

After the first discoveries in the spring, divers collected additional samples to fix the site’s age and boundaries. A second campaign brought in researchers from the Fraunhofer Institute in Ilmenau, who ran a remotely operated underwater vehicle with high-resolution sonar over the lake bed. The scans are recording the relief of the former shoreline so the team can map each find and see whether the timbers form recognizable structural patterns.

Marcel Weiß, the project leader, said proof of permanent structures or intensively shaped living space at such an early date would change how archaeologists understand hunter-gatherer societies and the origins of Europe’s cultural landscapes. For now the team is holding off on conclusions from single pieces of wood, he said, and working instead to establish how big the submerged site is.
