World archeology became aware of the Thracians in 1851. At that time, a Thracian treasure was found near the village of Rozovets at the foot of Sredna Gora mountain. Among the items is a gold ring, which is now part of the Louvre collection. The first Thracian tomb, which was completely discovered in 1931, is located near the village of Mezek, in Svilengrad Municipality. The largest collection of Thracian trapezoidal niches is located in the Deaf Stones area near Lyubimets. Other similar findings are around the Mineralni bani. From the Roman period there are impressive sites in Plovdiv and Stara Zagora. And this is only a very small part of the cultural and historical heritage of the area, among which places such as Yunatsite, Karanovo, Mal Tepe, Kabile, Paleokastro, Castra Rubra, Neutzikon shine. The connecting thread of the area is the Maritza River, known in ancient times as Rhombus and Hebros. Its lower reaches before the Delta were called Europe, which later gave the name of our entire continent. All this today is just Thrace – the impressive tourist region of Bulgaria.
