 Wilhelm Dörpfeld went to Athens in 1885 to look at the ruins of the Temple of Athena where he noticed some ruins were still standing and looked as though the architecture was the temple of Athena Polias.Wilhelm saw a piece of a building that looked like a piece of the Erechtheiom temple, which was in the same location another archaeologist named Ross excavated in 1834.Once Wilhelm saw the same ruins he cleared in 1834, Wilhelm went towards the ruins to examine and he immediately confirmed it was the old temple of Athena.
