Walking along the Via Aventina there is this length of tuff wall that hugs the base of the Aventine, and several hundred yards/meters in from the Aurelian wall. Our classics guide who works down the street said it was a part of the Servian wall. But I thought there wasn't this much of it left, and what existed was somewhere else. This is a big set of blocks. Is it part of the Servian wall?

Apparently so. According the Amanda Claridge (Rome: An Oxford Archaeological Guide) this is the second largest visible stretch of the Republican wall after the one next to Termini, and at this point on Via Aventino "the walls form a re-entrant to protect a gate, the porta Raudusculana".
