Living on the lake in the Iron Age: new results from aerial photographs, geophysical survey and dendrochronology on sites of Biskupin type

The island site of Biskupin with its densely planned interior bears an uncanny resemblance to a prison camp. Is it typical of the Iron Age in Northern Europe? The authors here explore neighbouring sites around Poznań using aerial photographs, geophysical survey and dendrochronology – to stunning effect. These low impact methods have given high impact results: dated street plans, some similar and others different from Biskupin, but within the same time frame: almost a repertoire of early urbanism. The authors must also be congratulated on the identification of a new type of Iron Age feature, the ‘open area for spouse avoidance’ defined at Sobiejuchy.
