On the left side of the road is first (near i, fig. 102) a small room with a good pavement of black and white marble. Built into a mediaeval wall in this room an architrave was found with the inscription:

The first half of this inscription was discovered in 1546; and the whole of it reads: in] honorem domus Augustae kalatores pontificium et flaminum. Accordingly the suggestion has been made that the subordinate officials of the priests had their office here at the corner of the Regia. The beautiful architectural fragments which lie here at present are worthy of notice, — pieces of entablature, capitals of columns and of pillars etc.: they belong to the restoration by Calvinus (B.C. 36).

A few steps to the left lie the foundations of the Regia of the republic. A room with a pavement of tufa slabs (d fig. 102) has in the centre a round substructure of grey tufa (the top layer is a modern restoration). It has been suggested, but without proper proof, that this was the Sacrarium Martis. It is equally improbable that a subterranean cistern (near f fig. 102) is the sanctuary of Ops. Farther on are to be seen the remains of the building of the empire. Of the south wall, which Calvinus decorated with the fasti consulares et triumphales, very little remains in situ; of the entablature however which crowned this south wall numerous fragments are lying about. This entablature belonged to the restoration by Septimius Severus. The remains of a wall, which are still standing upright, and also the tablets of the fasti themselves, shew that Calvinus's building was  p184 very small, but very costly, being built entirely of blocks of marble. Remains of a pavement of white marble, the threshold of a door (c fig. 102). etc. have been preserved.

In the early middle ages (VII‑VIII centuries) the entire north façade of the Regia, opposite the temple of Faustina, was transformed into part of a noble private residence, similar to the one which was built in the neighbouring Basilica Aemilia: to this building belong columns of cipollino with the ugly bases of red granite, and  p185 the walls built partly of brick and partly of blocks of marble.— The Regia of the republican period extended probably considerably farther toward the east. To this republican building are ascribed remains of tufa and travertine of all sorts which have been found under the foundations of the tabernae, between the house of the Vestals and the Sacra Via (near z fig. 113).
