The Erechteion is the most sacred temple of all temples of Athens.
The true name was the temple of Athena Polias. The whole building presents
a complex architecture due to the irregularity of the ground. It is composed
of a rectangular cella, divided in two sanctuaries built on different levels,
and flanked by three unequal porticoes. In the foreground is the high north portico
made of 4 ionic columns, and which was one of the masterpieces of the attic art (

In the middle is the west part of the temple, which was longer and on a 3 meters higher level. (

It is the sanctuary of Erechteus, and one could access to it through the north portico.
