The Porta Esquilina was a gate in the Servian Wall, of which the Arch of Gallienus is extant today. Tradition dates it back to the 6th century BC, when the Servian Wall was said to have been built by the Roman king Servius Tullius. However modern scholarship and evidence from archaeology indicate a date in the fourth century BC. The archway of the gate was rededicated in 262 as the Arch of Gallienus.

The Lateran Obelisk or Tekhen Waty in ancient Egyptian is the largest standing ancient Egyptian obelisk in the world, and it is also the tallest obelisk in Italy. It originally weighed 413 tonnes, but after collapsing and being re-erected 4 metres (13 ft) shorter, now weighs around 300 tonnes. It is located in Rome, in the square across from the Archbasilica of St. John Lateran and the San Giovanni Addolorata Hospital.
