The Rhodopes have a rich cultural heritage including ancient Thracian sites such as Perperikon, Tatul and Belintash, and medieval castles, churches, monasteries, and picturesque villages with traditional Bulgarian architecture from the 18th and 19th centuries.
[citation needed] In geomorphological terms, the Rhodopes are part of the Rila-Rhodope massif, which is the oldest landmass on the Balkan peninsula.
The mountains are famous for the largest coniferous woods in the Balkans, their mild relief and the lush vegetation in the western parts as well as the abundance of birds of prey in the eastern areas.
The location of the Rhodopes in the southeastern part of the Balkan Peninsula largely determines the climate in the region.
The Pamporovo resort, where the microclimate permits a heavy snow cover to be preserved for a long time, is an excellent example.
Temperatures as low as −15 °C (5 °F) are common in winter, and due to this the Rhodopes are the southernmost place in the Balkans where tree species such as the Norway Spruce and the Silver Birch can be found.
Some of the deepest river gorges in the Rhodopes are located in the western parts, as well as the rock phenomenon Wonderful Bridges.
Significant bodies of water include the Chaira lakes and the Dospat, Batak, Shiroka Polyana, Golyam Beglik and Tsigov Chark dams.
The town of Batak is also located in this part of the mountains, as well as the popular tourist centres Smolyan, Velingrad, Devin, Chepelare, the winter resort Pamporovo, the Eastern Orthodox Bachkovo Monastery, the ruins of the Asen dynasty's fortress, and the Devil's Throat, Yagodinska, and Uhlovitsa caves.
The highest village in Bulgaria, Manastir (over 1,500 meters (4,921 ft)), is crouched in the northern foot of Prespa Peak.
The Eastern Rhodopes are spread over a territory of about 34% of the mountains' area in Bulgaria, constituting a much lower part.
The depopulation of the region, that has not been grazed for more than 50 years, combined with high rainfall and its geographical location, has contributed to the creation and maintenance of a biological paradise.
Additionally, there are archeological sites throughout the region related to the cult of Dionysus, such as the ancient Thracian city of Perperikon.
The frequent mention of the Rhodope in Ancient Greek and Latin sources indicates that the mountain had played an important role in the political and religious life of the Thracian tribes that lived on it.
On the tops of the mountain there was a famous oracle, which they had visited to consult Alexander the Great and later the father of Octavian Augustus.
[8] In 2005, German scholars from the University of Heidelberg confirmed that the two rather small fragments discovered by archaeologist Nikolay Ovcharov in the Eastern Rhodopes mountains are written in the Minoan Linear A script from about 15th century BC.
[9] In the Middle Ages the mountain was part of the Bulgarian and Byzantine Empires and often changed hands between the two countries.
The mountains are also one of the regions associated with the Sarakatsani, a nomadic Greek people who traditionally roamed between Northern Thrace and the Aegean coast.
Due to the large Muslim population the number of pigs is relatively low but there are many sheep which are traditional for the Rhodopes.
The machine-building industry is developed in Smolyan, Kardzhali, Devin, Bratsigovo, Ivailovgrad and others; there is a pharmaceutical plant in Pestera.
The timber industry is developed mainly in the western parts where there are some of the most important forest massifs in the Balkan Peninsula.
The Rhodopes are one of the main hydro-power generation regions of Bulgaria with a number of major hydroelectric power plants such as Batak, Peshtera, Aleko, Studen Kladenets, Kardzhali, Vacha and Thisavros and Platanovrysi in Greece.
The ruins of castles, Thracian sites such as Perperikon and Tatul, the villages in National Revival style and the monasteries are also visited by many Bulgarian and foreign tourists.
