The Doric Propylon (or Prolylaia) – monumental entrance gate – to the Sanctuary of Poseidon. Made of poros stone and marble.
Material remains are rather little. In the photo above is the base of the gate structure. In the photo below is remain of a column.
The photo below was shot from the north; you can recognise how the propylon and the temple is positioned.
