Montenegro, set along the Adriatic Sea, draws travelers with its dramatic landscapes and layered history. The Bay of Kotor, often mistaken for a fjord, is actually a submerged river canyon surrounded by steep cliffs and medieval towns. Kotor itself, a UNESCO World Heritage site, is enclosed by ancient fortifications that visitors can climb for panoramic views stretching from terracotta rooftops to the sea.

Hong Kong, a Special Administrative Region of China, is a destination where skyscrapers meet the sea and mountains. Its dramatic skyline, best admired from Victoria Harbour or the Peak, reflects its role as a global financial hub.

Oslo, Norway’s capital, stands at the crossroads of Nordic history and forward-thinking design. Originally founded over a thousand years ago by Viking King Harald Hardrada, the city has evolved from a medieval trading hub into one of Europe’s most modern capitals. Visitors can explore its layered past at the Akershus Fortress, a 13th-century stronghold still standing guard over Oslofjord, or walk through the preserved wooden homes of Damstredet.

A series of gates surrounds the two centers of ancient, medieval Fez (sometimes spelled Fes). The principal axes link the center to the gates and a street surrounds the heart of the old city. The Kairouan quarter, which is longer, is crossed by an artery. Narrow, tortuous pedestrian streets, covered passages, stairs and numerous dead-ends make up the dense layout with few urban squares.

Silistra, a charming city located on the southern bank of the lower Danube River in Bulgaria, is a hidden gem that seamlessly blends ancient history with natural beauty. Founded by the Romans as Durostorum, Silistra is one of Bulgaria’s oldest cities, offering a wealth of historical sites that transport visitors back to the Roman Empire. The Silistra Roman Tomb, with its well-preserved frescoes, stands as a testament to the city’s rich past and is a must-visit for history enthusiasts.
