Today, its remains are found in the comune of Santa Maria Capua Vetere, on Piazza I Ottobre.

Some of the ornamental busts that were originally used as keystones for the arches of the amphitheatre are found today in the façade of the Palazzo del comune of Capua.

In 2024 the amphitheatre, along with ancient Capua as part of the Appian Way, has been recognised as a UNESCO World Heritage Site.

More remains can be seen in the National Archaeological Museum in Naples, such as the Venus of Capua, which was discovered in the general area of the amphitheatre.

It was restored by archaeologist Alessio Simmaco Mazzocchi, as follows: COLONIA IULIA FELIX AUGUSTA CAPUA FECIT DIVUS HADRIANUS AUG RESTITUIT IMAGINES ET COLUMNAS ADDI CURAVIT IMP CAES T AELIUS HADRIANUS ANTONINUS AUG PIUS DEDICAVITThe inscription, originally placed at the entrance to the amphitheatre, was put on display under the arch of the church of St Eligio a Capua, but is now conserved in the Museo Campano in Capua.

From the end of the 9th century, it was largely spoliated by the Capuans themselves following the transfer of the Civitas Capuana from its old Roman site to Casilinum (the current location of the town), especially for the construction of the Lombard castle.
