Ibiza is a single island that belongs to Spain.
== Tourism ===== Nightlife ===Ibiza is considered to be a popular tourist destination, especially due to its well-known and at times riotous nightclub-based nightlife centred on two areas: Ibiza Town, the island's capital on the southern shore and Sant Antoni to the west
 Ibiza negotiated a favorable treaty (Foedus) with the Romans, which spared Ibiza from further destruction and allowed it to continue its Carthaginian-Punic institutions, traditions and even coinage well into the Empire days, when it became an official Roman municipality
