Porta Querquetulana

Lawrence Richardson located it at the edge of Regio V Esquiliae, with the Clivus Scauri passing through it.

[5] In the early twenty-first century, photogrammetric data and 3D visualization have suggested that the grove of the Querquetulanae may have been incorporated into the Gardens of Maecenas.

A nymphaeum from the time of Hadrian would have replaced the natural spring within it.

In this view, the grove was located in Regio III, along the Via Labicana.

[7] Pliny places the Porta Querquetulana between Jupiter Fagutalis and the Viminal Hill, and thus within the Esquiline.
