Unmissable Eastern European garden - Serbia.

Serbia has beautiful scenery, dense river networks, and diverse landforms. The north is an agricultural cultivation base; the central region is a fruit planting area; gradually to the south, it becomes a mountainous and canyon area, with many caves and protected virgin forests. The Danube River flows through the country, and the history of many foreign invasions and rule has left a rich cultural heritage, including prehistoric archaeological sites, ancient Roman cultural sites, and a large number of medieval churches and monasteries, nurturing such a beautiful and low-key secret garden country in Eastern Europe. From Belgrade to Nis, its cities have unique characteristics. Belgrade: one of the top ten nightlife cities in the world; Subotica: a small town full of Hungarian style; Novi Sad: the "Athens" city with abundant knowledge; Nis: the city of slaughter and resistance in the past. Climb up the Kalemegdan Fortress, draped in the glow of the setting sun, and imagine the changes of time. Later, as the sun sets in the west, the gentle and charming Danube River and the bright moonlight will cover you with a cool night. The St. Sava Church is the largest Eastern Orthodox church on the surface of the earth, built in memory of St. Sava, the founder of the Serbian Orthodox Church and an important figure in medieval Serbia. The church is magnificent and solemn, with religious stories in the murals wrapped in brilliant colors, fascinating people.
