The Servian Wall was the first wall around Rome, built around the 3rd Century BC. This well-preserved section gives a good opportunity to see the construction methods used at that time, involving the use of blocks of tufa rock.
The Servian Wall is an ancient Roman defensive barrier constructed around the city of Rome in the early 4th century BC. The wall was built of volcanic tuff and was up to 10 m (33 ft) in height in places, 3.6 m (12 ft) wide at its base, 11 km (6.8 mi) long, and is believed to have had 16 main gates, of which only one or two have survived, and enclosed a total area of 246 hectares. In the 3rd century AD it was superseded by the construction of the larger Aurelian Walls as the city of Rome grew beyond the boundary of the Servian Wall.

The most popular thing on the Aventino hill is to take a peek through the keyhole that lets you look through three countries (the third is the Sovereign Military Order of Malta, which owns the building that the keyhole belongs to) and see St. Peter's Basilica in the Vatican City perfectly framed between two rows of trees.

Behind the pyramid, entered by the Via Caio Cestio, is the Protestant Cemetery where the poet John Keats was buried in 1821 and Percy Bysshe Shelley's ashes were also buried after his drowning in 1822. Richard Dana, author of Two Years before the Mast was buried there in 1882, and the Beat Generation poet Gregory Corso was buried there in 2001.
