the first known settlement from the early helladic period (3000-2000 bc) was located on the plain. a granary and several other buildings, as well as a pottery kiln, have been found so far. this settlement was moved to the top of the acropolis in the middle helladic period (2000-1600 bc) because the plain was flooded by the nearby lagoon. in the late helladic period (1600-1100 bc), the population dwindled and the remains found so far have been interpreted as an observation post. the site was abandoned during the greek dark ages.
