Porta Caelimontana e Porta Querquetulana, Ancient city gates on Caelian Hill, Rome, Italy.

Porta Caelimontana and Porta Querquetulana were two gates in the Servian Wall on the eastern side of the Caelian Hill in Rome; only the westernmost, Porta Caelimontana, survives. Its tuff blocks are still partly visible on the right, while the present travertine arch, known as the Arch of Dolabella and Silanus, replaced the gate in AD 10. The arch stands at the start of Via San Paolo della Croce, on the route of the ancient Clivus Scauri.

The surviving gate, the western Porta Caelimontana, was restored in the Augustan age. In AD 10 a travertine arch replaced the old tuff gate, still partly visible on the right, by senatorial decree under the consuls in office, as the plaque on the attic records. A restoration of 211, under Caracalla, made the arch carry the arches of the Neronian aqueduct.

The name Querquetulana comes from the Latin word for oak woods, recalling the forested land that once covered Caelian Hill before the city grew around it. Visitors who look closely at the surviving arch can still read the inscriptions naming the officials who paid for its construction.

The surviving arch is visible from street level and free to view from the outside without any entry fee. Since it sits on Caelian Hill, visitors coming from lower parts of Rome should be ready for a short uphill walk.

A friar named John of Matha lived in a small room built above the arch from 1209 until his death in 1213. His presence there shows how Roman ruins were turned into shelters for religious figures long after their original purpose had ended.
