The temple front has been converted by Alberti into wall-architecture, as Wittkower noted, and a complete series of pilasters, like pillars embedded in the wall, has been elided to the two outermost, and the two flanking Pellegrino Ardizoni's clumsy doorway, which overlaps them and ill suits its space.

The most unexpected motif in the façade is the central break in the entablature presented by the window opening, doubtless intended to be arch-headed under the arched entablature that joins the outer sections, a motif that Wittkower conjectured Alberti knew from the side elevations of the Roman
