Segesta

Small on-site museum displaying pottery, inscriptions, tools, and statues uncovered during excavations — useful for understanding the context of the ruins.

Iconic unfinished peripteral Doric temple (6×14 columns) built around 430–420 BC. Columns remain unfluted, and the cella was likely never roofed. Its purpose and dedication remain uncertain, though it's possibly linked to a non-Greek cult.

Remains of the valley gate and an adjacent necropolis dating from the Hellenistic period. In Roman times, the gate was reused as a mill.

Southern acropolis containing residential structures, notably the so-called "house of ships". The area was linked to the northern acropolis by a narrow saddle.

Main civic zone of the ancient city with remains of public buildings, agora, the theatre, a later medieval castle, mosque, necropolis, and a 15th-century church — all layered atop earlier structures.

Extensive remains of Segesta’s defensive system, developed over centuries. Includes stretches of wall from the 5th century BC, Roman-era upgrades, and multiple gates including Porta Stazzo, Porta Teatro, and Porta Bastione.

Scenic theatre built in the mid‑2nd century BC under Roman influence. Positioned on the northern acropolis with sweeping views. Summer performances sometimes take place here.
