The Archaeological Museum in Peccioli is located in piazza del Carmine, within a system of tunnels that were once used as underground tombs. The museum hosts artefacts discovered at the Etruscan archaeological site of Ortaglia, where a well was discovered, bringing several votive objects (many of them ex-voto) to light. Parts of a building were also found which, due to their size and decoration, suggest they were originally part of a temple. The presence of many sacred objects, typical of female labour, such as weights for weaving looms and reels for thread, indicate that the sanctuary was dedicated to a female divinity. The artefacts were found in fragments because the building collapsed following a fire, probably in the 4th century BCE.
The collection includes a splendid red-figure Attic kylix (wine glass), as well as the funerary hoard belonging to Etruscan tomb in Legoli and a great ceremonial basin for purifying oneself. Moreover, a big three-dimensional model reproduces the Tuscan temple, rebuilt according to the laws of Vitruvius (architectural theorist from the Augustine era).
