The early Samians worshipped the goddess Hera, believing she was born here beneath a bush near the stream Imbrassos and that there she also lay with Zeus. Several temples were subsequently built on the site in her honor, the earliest dating back to the 8th century BC. Polycrates rebuilt the To Hraio, or Temple of Hera, around 540 BC, making it four times larger than the Parthenon and the largest Greek temple ever conceived, with two rows of columns (155 in all).
The temple was damaged by fire in 525 BC and never completed, owing to Polycrates's untimely death. In the intervening years, masons recycled the stones to create other buildings, including a basilica (foundations remain at the site) to the Virgin Mary. Today you can only imagine the To Hraio's massive glory; of its forest of columns only one remains standing, slightly askew and only half its original height, amid acres of marble remnants in marshy ground thick with poppies.
At the ancient celebrations to honor Hera, the faithful approached from the sea along the Sacred Road, which is still visible at the site's northeast corner. Nearby are replicas of a 6th-century BC sculpture depicting an aristocratic family; its chiseled signature reads "Genelaos made me." The kouros from Heraion was found here, and now is in the Archaeological Museum in Samos town. Hours may be shortened in winter.
