Strandzha (Bulgarian: Странджа, also transliterated as Strandja; Turkish: Yıldız Dağları or Istranca) is a mountain massif in southeastern Bulgaria and the European part of Turkey, in the southeastern part of the Balkans between the plains of Thrace to the west, the lowlands near Burgas to the north and the Black Sea to the east. Its highest peak is Mahya Dağı (Bulgarian: Махиада, Mahiada) (1,031 m or 3,383 ft) in Turkey, while the highest point on Bulgarian territory is Golyamo Gradishte (Bulgarian: Голямо Градище) (710 m or 2,329 ft). The total area of the massif is approximately 10,000 km2 (3,861 sq mi). The name of the massif allegedly derives from Istranca, the former name of the Municipality of Binkılıç in Çatalca district, Istanbul province.
Geography and climate 
The climate of the area is considerably influenced by the Black Sea and is predominantly humid continental in the mountains and humid subtropical at the coast. Major rivers in the area are the Veleka (147 km or 91 mi long) and the border river Rezovska (112 km or 70 mi long).
Strandzha Natural Park 
Strandzha Natural Park, established in 1995 in the Bulgarian part of the massif, is the largest protected area in Bulgaria, embracing 1,161 km2 (448 sq mi), or about 1% of Bulgaria's total territory.
History and culture 
Inhabited by the Thracians in antiquity, Strandzha is an area with a large concentration of ruins of Thracian sanctuaries and sacrificial altars, dolmens and other archaeological objects.
The mountains were the site of the Bulgarian Preobrazhenie Uprising of 1903 that was crushed by Ottoman troops. The current Bulgarian-Turkish border in the region was established after the Balkan Wars of 1912-1913, when the northern part of Strandzha became part of Bulgaria.
Culturally, the Bulgarian part of Strandzha is known for the specific architecture that can be observed in Malko Tarnovo, Brashlyan and most other villages, the rich folklore and distinctive rituals, such as nestinarstvo (barefoot dancing on live embers), that preserve numerous pagan elements.
Flora and fauna 
The Strandzha Mountains have a rich and diverse flora and fauna, unique within Europe. 50% of Bulgaria's flora can be observed in Strandzha Nature Park and the area has 121 habitat types. In Strandzha over 600 different species of invertebrates are found, as well as over 400 species of vertebrates, 41 species of freshwater fish, 10 species of amphibians, over 20 different species of reptile, more than 130 species of breeding birds, and over 60 different species of mammals.
One of the reasons for the abundance of flora and fauna in Strandzha is the area's geographical location at a bio-geographical crossroad between the European and Asian continents.
The plant communities in Strandzha developed before Europe was separated from Asia by the formation of the Bosporus Strait that now connects the Black Sea with the Mediterranean Sea. Land-ice never reached Strandzha during the ice-ages of the Pleistocene and the Holocene and this lack of glaciations has helped create the circumstances in which flora characteristic for the Tertiary period on the European continent has been preserved in Strandzha.
