Segesta
Ancient Egesta was founded by the Elymians, a people of Anatolian origin, possibly before 1100 BC. The Greeks arrived in the region some 5 centuries later and rapidly Hellinized the city, which soon found itself in a rivalry with Selinunte to the south. Though never actually completed (therefore lacking fluting on the columns), Segesta's temple is perhaps the best preserved in the ancient Greek world. The temple is right near the main entry area, but the hilltop amphitheatre and archeological site are well worth a visit and there are frequent shuttles if you don't want to make the ascent on foot. Segesta was abandoned in the Middle Ages, and there are ruins of a few medieval structures, such as the apse of a Norman-era church. Like the temples of Selinunte and Paestum (south of Naples), Segesta is in the country far from the city, and that's part of its eternal appeal: no modern urban eyesores cluttering the serene scenery.
Bottom Line: Better than Agrigento. MUCH better. And in the spring, with the green fields and blooming wildflowers it's a stunning sight.
Getting There: From Palermo or Trapani (and Erice), take the A29 to the Segesta exit.
Dining: This isolated site is not near any restaurants; Calatafimi is the nearest town.
