Grandi Cavi is the name of another ancient quarry. It is situated on the eastern bank of the River Modione, which flows into the sea at Selinunte, and is shown on the map as Latomie. It is 7km/4mi east of Campobello and can also be reached from Castelvetrano (about 5km/3mi in a southeasterly direction on a side-road which runs parallel to the SS 115).
On the Piazza Garibaldi, the central point of Castelvetrano, stands the Chiesa Madre (16th century) with a rich doorway and an interior decorated with stucco, in front of which are the Fontana della Ninfa of 1615 and the town hall. The latter contains a small archeological collection, which included the bronze statue of the Ephebe of Selinunte, until in 1962 it was stolen from the mayor's chamber. It reappeared in 1968 and is now kept in the museum in Palermo.
In San Giovanni in Castelvetrano, which dates from the end of the 18th century and was built on the remains of an earlier 16th century building, there is a Madonna di Loreto (1489) and a statue of John the Baptist by Antonello Gagini (1522).
