Filmed at the dig site in Kythera, archaeologist Geli Fragou explains how the walls uncovered in Trench A were built, and are much thicker than those used in houses.
A range of evidence suggests that this building was a commercial structure, part of the ancient marketplace or Agora.
Interestingly, a large column from an older temple or public building was used in the base of one of this building's walls. The column was possibly carved 60-80 years earlier and reused after the public building or temple it was made for suffered some sort of catastrophe.
Perhaps a natural disaster, or something else?
We don't know... yet.
Evidence suggests that there was some sort of mishap which, until now remains undocumented.
Hopefully the mystery will be solved in coming excavation seasons.
