All around the temple ran a colonnade, the sides each consisting of seven square pillars, without capital or base, and the two facades, front and back, being supported by two columns with the lotus-bud capital.

Both pillars and columns rose direct from the parapet; except on the east front, where a flight of ten or twelve steps, enclosed between two walls of the same height as the platform, led up to the _cella_.

The two columns at the head of the steps were wider apart than those of the opposite face, and through the space thus opened was seen a richly-decorated door.

A second door opened at the other end, beneath the portico.

Later, in Roman times, this feature was utilised in altering the building.
