The columned, round-headed windows are set in deeply between the pillars which carry the massive entablature, and this again is surmounted by a balustrade with obelisks at each angle and figures marking the line of each bay.
Within this raised gallery, which is sheltered by the oversailing eaves, there is, in the larger temples, a columned loggia passing round the two sides and the front of the building, or, in some cases, placed on the faade only.
The main front was a five-bay, two-storey, stuccoed block with Tuscan pilasters and a central, columned porch.
