MEDIEVAL REUSE | Archaeologists discover a ship hidden in a ceiling after 800 years mistaken for ordinary beams

For around 800 years, people thought it was simply a ceiling. Archaeologists examining a modest basement in Konstanz’s old town have now found something far more extraordinary: almost an entire ship’s hull hidden inside it.

The building, located near Lake Constance in southern Germany, turned out to be a rare time capsule of medieval shipbuilding. What appeared to be ordinary reused material was instead made up of carefully fitted elements from a vessel.

The details and unusual repairs could reveal how people approached engineering and construction 800 years ago. The discovery may prove more informative than wrecks lying on the lakebed, because the basement ceiling preserves the ship’s construction in a different setting.
