Archaeologists uncover large 14th-century stone cellar at Berlin's Molkenmarkt excavation

The discovery

Archaeologists working at the Molkenmarkt in Berlin's historic Mitte district have uncovered the remains of a previously unknown medieval structure. The Landesdenkmalamt Berlin (State Monuments Office) announced the find during a press tour, identifying it as a large stone cellar dating from the 14th or early 15th century. The cellar measures at least 8.50 metres in length and almost 7.50 metres in width, making it unusually large for its period.

The stone cellar possibly served as a trading and commercial cellar and belonged to a previously unknown, large and representative building of the late Middle Ages.

Among the features uncovered are wall remains, niches, and openings for light and ventilation. The discovery is considered unusual not only for its size but also because the cellar survived largely intact through centuries of rebuilding and modification.

Survival and destruction

The cellar retained its basic structure through multiple renovations over the centuries. It was ultimately destroyed by wartime action, according to the Landesdenkmalamt. The filling and sealing of the site after 1945 contributed to the remains being preserved in unusually good condition. The post-war layers effectively capped the medieval structure, shielding it from further environmental degradation.

The Molkenmarkt excavation project

Excavations at the Molkenmarkt have been underway since 2019 and are scheduled to continue until 2027. Bausenator Christian Gaebler (SPD) described the project as one of the largest urban archaeological investigations in Germany. The scale and duration of the dig reflect the historical density of the area, which sits at the core of old Berlin.

Next steps for the find

In the coming days, the exposed cellar will be temporarily backfilled to protect it from environmental influences. This is standard practice for fragile archaeological features that cannot be immediately integrated into a permanent display or conservation structure. The backfilling ensures the medieval masonry remains stable while the broader excavation project continues through its planned 2027 endpoint.
