Kerak is a fortress town 75 miles (120km) from Amman, and contains one of the two major Crusader castles in the Kingdom. The castle, built to protect the approach to Jerusalem, stands on a craggy plateau 4,300ft above sea level. It was built in the early part of the 12th century and held for 50 years by the Crusaders until they were defeated by Salah al Din (Saladin) in 1189.

Gotland, Sweden’s largest island, sits in the Baltic Sea and feels like a world of its own. Its main town, Visby, is a UNESCO World Heritage site and one of the best-preserved medieval towns in Northern Europe. Surrounded by a 3.5-kilometer stone wall with original towers still intact, Visby once served as a key Hanseatic trading hub. Visitors can walk along cobbled streets lined with rose-covered cottages, explore Gothic church ruins, and climb up the city wall for views over the harbor.

Kunming, the capital of China’s Yunnan Province, is often called the “City of Eternal Spring” for its mild climate and blooming flowers year-round. Perched on a plateau more than 6,000 feet above sea level, Kunming has long served as a crossroads of cultures and trade routes connecting China to Southeast Asia.

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.

Bamberg, located in northern Bavaria, stands out for its remarkably preserved medieval layout, which earned it a spot on the UNESCO World Heritage list. Built on seven hills and often compared to Rome for that reason, the city’s architecture reflects over a thousand years of uninterrupted development. Bamberg is well known for its beer, and not just in the usual Bavarian sense. The city has more breweries per capita than any other town in Germany, and it’s the birthplace of rauchbier.
