I believe the correct answer is: Sicyon in northern Peloponesus.

The Greek geographer Pausanias described Greece in ten books, beginning his journey in Attica. Pausanias visited the city of Sicyon in northern Peloponesus, in which he saw and later described the temple of Demeter and the statue of Poseidon.
