Two Temples Squished Into One: The Erechtheion's Ten-Foot Split
The Erechtheion is essentially two temples squished into one, split across two elevations. Its eastern portico sits on the higher ground and marks the entrance to the part of the temple dedicated to Athena Polias. A revered olive-wood statue of the goddess was housed in that inner room.
The northern portico is about ten feet lower than the eastern one, and it serves as the entrance to the western section of the temple. That lower section holds shrines to Poseidon-Erechtheus, Hephaistos, and Boutes, an arrangement that challenges the Greek canon of the perfectly arranged, symmetrical temple. Why it looks that way is complicated, and scholars are still debating it.

Athena Polias gets the higher entrance while Poseidon-Erechtheus, Hephaistos, and Boutes sit about ten feet below, which makes it tempting to read the building as ranking its gods by altitude.
It does challenge the canon of the symmetrical temple, but the reason for the layout is complicated and still argued over, so altitude-as-hierarchy stays one reading rather than the answer.
