Archaeologists in Berlin have made a remarkable discovery beneath the cobblestones of Molkenmarkt, one of the oldest squares in the city’s historic Mitte district. During ongoing excavations, a large medieval stone cellar dating from the 14th or early 15th century was uncovered — the remains of a previously unknown building that once stood proudly in medieval Berlin.
The cellar is considered unusual for its size. It measures at least 8.50 meters in length and nearly 7.50 meters in width, making it one of the larger medieval storage cellars found in the city. Despite several renovations and expansions over the centuries, the cellar’s basic structure remained intact for hundreds of years — until the building above was destroyed during World War II.
Eberhard Völker, the project’s scientific director from the Berlin State Office for the Preservation of Historical Monuments, explained that the stone cellar likely served as a storage and trading cellar and was part of a large and imposing late-medieval building. The excavation also uncovered remnants of walls, niches, and openings for light and ventilation, giving researchers a fascinating glimpse into medieval Berlin’s urban architecture.
Senator for Urban Development Christian Gaebler visited the site and highlighted the significance of the find. He noted that the excavations at Molkenmarkt, which have been underway since 2019, represent one of the largest urban archaeological investigations in Germany. The work is expected to continue until 2027, promising even more discoveries as researchers dig deeper into Berlin’s layered past.
In the coming days, the excavated cellar will be carefully documented and preserved. The discovery adds another piece to the puzzle of medieval Berlin, a city whose history stretches back over 800 years. For history enthusiasts and visitors to Berlin, Molkenmarkt is already known as a charming square with cafés and historic buildings — and now it has an even richer story to tell.
Berlin continues to reveal surprises beneath its streets, reminding us that the city’s history is still being uncovered one stone at a time.
