How was the erechtheion built?

The Erechtheion was constructed between 421 and 406 BCE on the Acropolis of Athens, designed by the architect Mnesicles. Its complex, asymmetrical layout was influenced by the uneven terrain, and it featured multiple levels to accommodate the sacred sites dedicated to Athena and Poseidon. The building is renowned for its distinctive architectural elements, including the Caryatids of the Porch of the Maidens, which replaced traditional columns with elegantly draped female figures, showcasing the artistry of the period. The Erechtheion's design reflects its dual religious significance and its integration into the landscape of the Acropolis.
