study showed that the construction had proceeded in two stages during 18 years, and after a break of 22 years, the work had been finished 40–42 years after the work had begun. During the first years, the construction consisted of two rectangular surfaces, which were delimited by rows of oak stakes and the surfaces were placed in an oblique angle. Each rectangle was ca 200 m² and were separated into eight or nine rooms. Most of the rooms had floors of logs. The reconstructions and the additions were partly motivated by fires, and the construction finally measured 1000 m². The construction was connected with the shore by footbridges on both sides. The size of the pile dwelling indicates that it was a communal work. It was also no fortification, because the stilts are too sparse and pushed into the bottom of the swamp too shallowly. The location in the swamp is also unfit for practical work, and the settlements were located on the arable soil around the swamp.


Early use as a cult centre

The pile dwelling was only inhabited during certain summer months. It was the tribe's or the clan's social centre where they gathered for festivities, especially after the summer's hunting and harvesting season. There are about 100 hearths of
