The Servian Wall
The Servian wall is attributed to and takes its name from the 6th Roman
king, Servius Tullius. Archeologists feel that it dates from
378 BC. It was a fortification of 11 km with 12 gates.
One can trace the wall from the Pons Sublicius at the Tiber, along the
Capitoline Hill, then north to the Quirinal and Viminal Hills, and south
to the Esquiline Hill. At the Caelius and Palatine the wall crossed
the Via Appia. It was here that one found the Porta Capena. The wall
continued around the Aventine connecting again with the Pons Sublicius.
