Professor Lucy Blue speaks with archaeologist Dr Harald Lübke from the Leibniz Centre for Archaeology about a recent discovery in the Baltic Sea off Germany that may be Europe’s oldest human-made underwater megastructure. Christened the ‘Blinkerwall’, it’s a continuous low wall made of hundreds of granite stones that stretches for around a kilometre. Could it have been constructed by hunter-gathers more than 10,000 years ago and if so, what was its purpose? Hear how by bringing together archaeologists, geophysicists and experts in landscape reconstruction the team is piecing together a now submerged landscape that was very different than the one today.

The project team includes:

Maine Geophysics:  Peter Feldens, IOW & Jens Schneider von Deimling, CAU Kiel

Marine Geology: Jacob Geersen, IOW

Archaeology: Jens Auer, LaKD MV,  Marcel Bradtmöller, Univ. Rostock, & Harald Lübke, LEIZA
