euthynteria

The uppermost layer, the 'euthynteria', partially protrudes above the ground level.

Euthynteria is the ancient Greek term for the uppermost course of a building's foundations, partly emerging from groundline.

The crepidoma rests on the euthynteria (foundation), which is normally constructed of locally available stone for the sake of economy.

The superstructure of the building (stereobate and stylobate, columns, walls, and entablature) were set on the euthynteria.
