Secret underground structures discovered beneath ancient Roman amphitheatre in Cartagena

RADARS have revealed an incredible archaeological discovery: the presence of hidden underground structures beneath the Roman amphitheatre in Cartagena. Early data gathered from these non-invasive radars suggests that the ancient monument is much larger than experts originally believed.

Secrets hidden beneath the stone: Cartagena’s history, deeper than experts originally thought

Dating back to the 1st century AD, the historic amphitheatre was previously thought to be able to hold between 10,000 and 11,000 spectators. However, these recent underground surveys have identified previously unknown corridors, entrances, and boundaries that were used by crowds, gladiators, and animals nearly 2,000 years ago. 

Unlocking ancient corridors without digging

These radars allow experts to see beneath the ground without having to dig. According to Cartagena’s Councillor for Heritage Pablo Braquehais, these newly discovered structures will be invaluable for crafting an accurate picture of the historic entertainment arena, and will help to guide future excavation projects.

In the future, local authorities are planning to open the amphitheatre permanently to the public, allowing interested visitors to watch live archaeological excavations as they are carried out. Previous digs at the site have already uncovered discoveries including service rooms and animal enclosures below the arena floor.

Live excavations and a two-million-euro investment

Looking forward, Cartagena authorities are also investing some €2 million into the site, hoping to yield more archaeological discoveries. This funding will help to complete excavations in the area, preserve part of the former bullring that was built above the amphitheatre, and help to expand the walkable areas for curious visitors and history buffs.

These latest radar anomalies promise to reveal even more about daily operations and behind-the-scenes life in one of Spain’s most historically significant cities. With the new discovery, the Costa Calida city of Cartagena continues to reaffirm its reputation as a top historical hub in Murcia, defined by its fascinating roots and bustling museum culture.
