TheColline Gate (LatinPorta Collina) was a landmark inancient Rome, supposed to have been built byServius Tullius, semi-legendaryking of Rome 578–535 BC. The gate stood at the north end of theServian Wall, and past it were two important streets, theVia Salaria andVia Nomentana. Within this area theAlta Semita linked theQuirinal with thePorta Carmentalis.[1] Several temples were located near the gate, including temples ofVenus Erycina[2] andFortuna. To a person facing the gate in the 4th century AD, theGardens of Sallust would have been on the left, with theBaths of Diocletian on the right.[3]
Plutarch says that, when aVestal was punished for violating her vow of chastity, the subterranean chamber for her live burial was near the Colline Gate.[4] The gate was thesite of a decisive battle during theRoman civil wars of the 80s BC between the forces ofCinna andSulla.[5]
