The platform for the judgment-seat (-tribunal-), and the stage whence the burgesses were addressed (the later rostra), were likewise erected on the -comitium- itself.

Its prolongation in the direction of the Velia became the new market (-forum Romanum-).
At the end of the latter, beneath the Palatine, rose the community-house, which included the official dwelling of the king (-regia-) and the common hearth of the city, the rotunda forming the temple of Vesta; at no great distance, on the south side of the Forum, there was erected a second round building connected with the former, the store-room of the community or temple of the Penates, which still stands at the present day as the porch of the church Santi Cosma e Damiano.

It is a feature significant of the new city now united in a way very different from the settlement of the "seven mounts," that, over and above the hearths of the thirty curies which the Palatine Rome had been content with associating in one building, the Servian Rome presented this general and single hearth for the city at large.( 15) Along the two longer sides of the Forum butchers' shops and other traders' stalls were arranged.

In the valley between the Palatine and Aventine a "ring" was staked off for races; this became the Circus.

The cattle-market was laid out immediately adjoining the river, and this soon became one of the most densely peopled quarters of Rome.
