Serbia is a country where centuries-old monasteries sit just a short drive from lively cities, and where the past is never far from daily life. In Belgrade, the capital, Kalemegdan Fortress offers panoramic views where the Danube meets the Sava River. This fortress has witnessed more than 100 battles and been rebuilt many times over two millennia. Within its walls are Roman ruins, an open-air military museum, and quiet park paths perfect for wandering between centuries of layered history.

Sognefjord, often called the “King of the Fjords,” is the longest and deepest fjord in Norway, stretching more than 200 kilometers inland from the North Sea. Towering cliffs rise dramatically on both sides of the water, some reaching over 1,000 meters high. Its size alone makes it a natural wonder, but what truly sets it apart is how the landscape changes along its length from wide, tranquil stretches to narrow passages where waterfalls plunge down sheer rock walls.
