Kotor is a coastal town in Montenegro. It is located in a secluded part of the Gulf of Kotor. The city has a population of 13,510 and is the administrative center of Kotor Municipality.

The old Mediterranean port of Kotor is surrounded by fortifications built during the Venetian period. It is located on the Bay of Kotor (Boka Kotorska), one of the most indented parts of the Adriatic Sea. Some have called it the southern-most fjord in Europe, but it is a ria, a submerged river canyon. Together with the nearly overhanging limestone cliffs of Orjen and Lovćen, Kotor and its surrounding area form an impressive landscape.

Since the early 2000s Kotor has seen an increase in tourists , many of them coming by cruise ship. Visitors are attracted by the natural environment of the Gulf of Kotor and by the old town of Kotor. Kotor is part of the World Heritage Site dubbed the Natural and Culturo-Historical Region of Kotor.

The fortified city of Kotor was also included in UNESCO's World Heritage Site list as part of Venetian Works of Defence between 15th and 17th centuries: Stato da Terra – western Stato da Mar in 201

Santorini, classically Thera, and officially Thira, is an island in the southern Aegean Sea, about 200 km (120 mi) southeast of Greece's mainland. It is the largest island of a small, circular archipelago, which bears the same name and is the remnant of a volcanic caldera. It forms the southernmost member of the Cyclades group of islands, with an area of approximately 73 km2 (28 sq mi) and a 2011 census population of 15,550. The municipality of Santorini includes the inhabited islands of Santorini and Therasia and the uninhabited islands of Nea Kameni, Palaia Kameni, Aspronisi, and Christiana. The total land area is 90.623 km2 (34.990 sq mi).Santorini is part of the Thira regional unit.

The island was the site of one of the largest volcanic eruptions in recorded history: the Minoan eruption(sometimes called the Thera eruption), which occurred about 3,600 years ago at the height of the Minoan civilization. The eruption left a large caldera surrounded by volcanic ash deposits hundreds of metres deep. It may have led indirectly to the collapse of the Minoan civilization on the island of Crete, 110 km (68 mi) to the south, through a gigantic tsunami. Another popular theory holds that the Thera eruption is the source of the legend of Atlantis.

It is the most active volcanic centre in the South Aegean Volcanic Arc, though what remains today is chiefly a water-filled caldera. The volcanic arc is approximately 500 km (310 mi) long and 20 to 40 km (12 to 25 mi) wide. The region first became volcanically active around 3–4 million years ago[citation needed], though volcanism on Thera began around 2 million years ago with the extrusion of dacitic lavas from vents around the Akrotiri.
