The Temple of the Dioscuri is one of the most recognisable ruins in Agrigento's Valley of the Temples, even though what you see today is a 19th-century reconstruction using fragments from the wider site. The four standing columns and corner entablature make a compact, memorable silhouette near Porta V.
It was probably built in the mid-5th century BC as a Doric temple, though the original dedication remains debated. Treat it as part of a longer walk through the archaeological park rather than a stand-alone stop.
