Chuuk, one of the four states of the Federated States of Micronesia, is best known for its vast lagoon which is one of the largest enclosed lagoons in the world. But what sets Chuuk apart is what lies beneath those calm blue waters: an entire underwater fleet of sunken warships, aircraft, and submarines left from World War II. Often called the "Ghost Fleet of Truk Lagoon," these wrecks make Chuuk a global destination for experienced divers.

Alberobello in southern Italy’s Puglia region captures the imagination with its distinctive trulli houses. These structures were built using a dry-stone technique passed down over centuries, without mortar or cement, and their unique form comes from layer upon layer of limestone nestled from nearby fields. Alberobello’s trulli are so remarkable that in 1996 the historic center was inscribed as a UNESCO World Heritage Site, where more than 1,600 of these buildings still stand.
