The Cagliari amphitheatre, which was built in the II century AD. today is a centre for lyric and theatrical shows. The steps are carved almost completely in the rock taking advantage of the slanted ground. The central underground hole that was dug along the main axis is still noticeable in the middle of the arena and it was intersected by an underground corridor accessible through two opposite staircases by the sides of the arena itself. There are only traces left of the works in cement used to integrate a natural opening in the rock that interrupted the terraces on the north-eastern side and closed the amphitheatre in on the opposite side; whilst the blocks used during the restoration works in the early 1900s' are more evident.
The terraces have gone through high degrade in the course of the centuries, when they To get there from the centre of Cagliari from Via Roma, take Largo Carlo Felice to PiazzaYenne and turn left into Corso Vittorio Emanuele, then turn right into Via Tigellio and left again into Viale Fra’ Ignazio da Laconi. Go past the Botanic Garden; the entrance to the amphitheatre is a bit further on the right.
