We present a complete, video-based 3d documentation process for the submerged remains of Neolithic pile dwellings at the UNESCO World Heritage Site "See am Mondsee" in Austria.

The recorded site is a Neolithic lake village dating to the 4th millenium BC. Based on initial reconstruction results, we

The campaign was accompanied by a German television film crew. Their documentary was shown on the German public television (ARD) broadcast "W wie Wissen".
