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.

Potsdam, the capital of Germany’s Brandenburg state, lies just southwest of Berlin and is best known for its grand palaces, landscaped gardens, and role as a seat of Prussian royalty.

Southampton is a city shaped by the sea. Located on the southern coast of England, it has been a key maritime port for centuries. In 1912, the RMS Titanic set sail from its docks, and today, the SeaCity Museum tells the story through the lives of local residents connected to the voyage. The medieval city walls, which are some of the best-preserved in England, still stand, offering a walk through time with views of old merchant houses, towers, and hidden vaults once used to store wine and wool.
