These small islands, sparkling like jewels in the Pacific Ocean, will make you discover the colors that excite your imagination. Discovered by marine navigators nearly four thousand years ago, the Mariana Islands benefit from a natural beauty shaped by the impressive power of volcanoes, swell, and sunshine. Marked by the successive Spanish, German settlements and finally Japanese, the islands keep vestiges of these successive periods whose end point will be the terrible battles with the Americans during the Second World War. Remained under American rule at the end of the conflict, the Mariana Islands have become an American territory in its own right. And now it’s up to you to discover the wonders of these islands.
