Took me about a month to get around to getting these developed. This is the Erechtheion, a temple to Athena and Poseidon on the top of the Acropolis in Athens.
It commemorates the popular Greek myth that tells the story of the founding of Athens. Crecops I, the first king of Athens, presided over a competition between Poseidon, god of the sea, and Athena, goddess of wisdom. Both deities were to give a gift to the people and whoever gave the best gift would become the city's patron deity. Poseidon struck his mighty trident against the top of the mountain and a fountain sprung from inside it. Athena gifted the people and olive tree. Being the god of the sea, Poseidon's fountain only gave salt water and so the wisdom goddess won. The city was named Athina in her honour, or Athens in English. Fun fact: Athena's symbol was the owl, which is why owls are regarded as wise even today.
