The Erechtheion, part of the Acropolis, Athens Greece.
The date of the construction of the building is unclear with current research indicating a date of around 430 BCE.
The building was damaged by fire in 377 BCE and again in the first cent BCE resulting in repairs and changes to the building in addition the usage of the building changed over the period as it was used by various cults and sects.
Current consensus is that it may have originally been a temple for the combined worship of Athena and Poseidon-Erechtheus
