Fountain of Piazza Castello is one of the historic places of Santo Stefano Quisquina. There is a residence of the Prince of Belmonte there, unfortunately now a private house. The place is very suggestive, with a small corner with benches and trees to sit and relax, very popular with the inhabitants. In the evening, the square retains its suggestiveness, and it is possible to spend a pleasant evening at 1900, a ristopub.
