The town is also famous for the Corinth Canal, which gives ships a route through the isthmus of Corinth. There are many things to do in the Corinth area, including an adrenaline rushing bungee jump. Another place to visit is the most important monument in Ancient Corinth, the imposing Doric Temple of Apollo. It lies on a low hill and dominates the site. This temple was built around 540 BC, on the site of an earlier seventh-century-BC temple. Today, only seven monolithic limestone columns remain, but originally there would have been six along the front and back of the temple, and fifteen down each side.
