Portico of Philo
The architectural remains that are today visible, relate mainly to the classical Telesterion (5th cent. BC), the Portico of Philo (4th cent. BC) and the Roman modifications (2nd cent. AD).
The Portico of Philo was attached to the east façade and its planning was undertaken by the Eleusinian architect Philo. It was founded on a strongly built substructure and its floor was paved with eleusinian limestone. It was of the Doric order with twelve columns on the façade and two on the narrow sides, of which only parts of the lower drums are preserved.
