Castello Eurialo, Military fortress in Syracuse, Italy
Castello Eurialo is an ancient Greek military fortress perched on a hilltop outside Syracuse, featuring thick stone walls, underground tunnels, and multiple defensive structures. The ruins spread across the landscape and show clearly how the Greeks built their protective fortifications.
Built in the early 4th century BCE under Dionysius I of Syracuse, this fortress served as a key defensive structure for the city's protection. It witnessed the region's major conflicts and remained strategically important throughout antiquity.
This fortress represents the engineering knowledge of ancient Syracuse and shows how the Greeks defended their territory. Walking through it gives a sense of the city's former military importance in the ancient Mediterranean.
Wear sturdy shoes as the terrain is uneven and some passages are steep, especially the stairs leading to underground sections. There is little shade across the site, so visiting early in the day and bringing plenty of water makes the experience more comfortable.
The underground passages and chambers were designed to allow soldiers to move safely during sieges and attacks. These innovative tunnel systems reveal how advanced ancient military engineering truly was.
