Isola del Giglio is an Italian island and comune situated in the Tyrrhenian Sea, off the coast of Tuscany, and is part of the Province of Grosseto. The island is one of seven that form the Tuscan Archipelago, lying within the Arcipelago Toscano National Park. Giglio means "lily" in Italian, and though the name would appear consistent with the insignia of Medici Florence, it derives from Aegilium, "Goat Island", a Latin transliteration of the Greek word for "little goat".
The island houses the remains of a Roman villa of Domitius Ahenobarbus (1st-2nd century), in the area of Giglio Porto (Giglio port). No traces of the once existing Temple of Diana can be seen now. The church of San Pietro Apostolo in Giglio Castello (Giglio castle) has an ivory crucifix attributed to the sculptor Giambologna. The island is also the site of an Etruscan shipwreck dating back to the early Iron age, c. 600 BC. The cargo of the ship included copper and lead ingots, iron spits, amphorae and a Corinthian helmet. Even a wooden writing tablet with stylus was preserved. The finds are almost completely lost now.
