Ibiza is a very popular tourist destination, especially due to its legendary and at times riotous nightlife centered around two areas: Ibiza Town, the island's capital on the eastern shore andSant Antoni to the West. Ciudad de Ibiza, which was founded by the Carthaginians 2,500 years ago, is located on top of a small hill. Surrounded by a couple of fortresses, the stronghold still proudly dominates the bay and the harbour at her feet. The city of Ibiza offers a unique and colorfulambience with its narrow lanes and numerous shops and stands, where you can buy souvenirs and the latest fashion articles.
