It is part of the so-called Trail of the Eagle's Nests, a hiking trail along a chain of 25 medieval castles between Częstochowa and Kraków.

9 The Cathedral Of St. Andrew, Scotland

It may be 865 years old, but the Cathedral of St. Andrew in Fife, Scotland, continues to ensnare tourists from around the world. This ruined cathedral was the center of the Medieval Catholic Church in Scotland since 1158 but fell into disuse after Catholic mass was outlawed during the 16th-century Scottish Reformation.

Today, the cathedral's St. Rule's Tower in the east serves as a land-and-sea mark, guiding thousands of pilgrims. Towering at 33 meters, it was originally ascended using ladders between wooden floors, but a stone spiral staircase was installed in the 18th century. Beneath this prominent tower built in grey sandstone ashlar is the burial ground for centuries-old bishops.

2 Cappadocia, Turkey

To many travelers, the Cappadocia region of Turkey is the best location in the world for hot air ballooning. Why Cappadocia? It is because the exceptional natural wonders of Cappadocia are more impressive when viewed from the air. The region's "fairy chimneys" (rock formations) and stunning landscapes are a wonder to behold.

Thousands of years ago, the rocks near Göreme eroded into hundreds of spectacular pillars and tower-like forms. The villagers then carved out houses, churches, and monasteries from the soft rocks of volcanic deposits. Göreme became a monastic center in 300– 1200 AD. Travelers must not miss the underground cities and the historic mansions and cave houses at the heart of Cappadocia.

March-May and September-November are the best times to visit Cappadocia. It isn’t peak season, and the weather is moderate.

1 Petra, Jordan

To say that Petra is enthralling is an understatement. Petra, also known as the Rose City, was carved directly into the red sandstone cliffs, creating a series of stunning rock-cut tombs, temples, and other structures. These are the remains of a lost civilization found by western explorers in the early 1800s.

Today, Petra is one of the world's most famous archeological sites, but many mysteries of the city remain. It might seem like a city of tombs, except that archeologists still don't know who was buried in each tomb. It has been said that only five percent of Petra has been uncovered. What is known today is that the Nabataeans who built the city more than 2,000 years ago have extraordinary skills and creativity.
