The Museo Regionale di Aidone, 15 km northeast of Piazza Armerina, houses the finest objects from the ancient Greek city of Morgantina. The collection's centrepiece is the Venere di Morgantina — a 5th-century BC acrolithic cult statue (made of limestone with marble face and limbs) — returned from the Getty Museum in 2011 after being looted in the 1970s.
The museum also holds other significant finds from Morgantina: Hellenistic silver treasure (the Morgantina Silver, some pieces still at American museums), terracottas, pottery, and architectural fragments. Combined with a visit to the Morgantina archaeological site itself (a short drive from Aidone), this makes a strong half-day alternative to the more famous Villa Romana.
