Balkan Mountains

The Balkan mountain range is located in the eastern part of the Balkan peninsula in Southeastern Europe. It is conventionally taken to begin at the peak of Vrashka Chuka on the border between Bulgaria and Serbia. It then runs for about 560 kilometres (350 mi), first in a south-easterly direction along the border, then eastward across Bulgaria, forming a natural barrier between the northern and southern halves of the country, before finally reaching the Black Sea at Cape Emine. The mountains reach their highest point with Botev Peak at 2,376 metres (7,795 ft).

In much of the central and eastern sections, the summit forms the watershed between the drainage basins of the Black Sea and the Aegean. A prominent gap in the mountains is formed by the predominantly narrow Iskar Gorge, a few miles north of the Bulgarian capital, Sofia. The karst relief determines the large number of caves, including Magura, featuring the most important and extended European post-Palaeolithic cave painting, Ledenika, Saeva dupka, Bacho Kiro, etc. The most notable rock formation are the Belogradchik Rocks in the west.

There are several important protected areas: Central Balkan National Park, Vrachanski Balkan, Bulgarka and Sinite Kamani, as well as a number of nature reserves. The Balkan Mountains are remarkable for their flora and fauna. Edelweiss grows there in the region of Kozyata stena. Some of the most striking landscapes are included in the Central Balkan National Park with steep cliffs, the highest waterfalls in the Balkans and lush vegetation. There are a number of important nature reserves such as Chuprene, Kozyata stena and others. Most of Europe's large mammals inhabit the area including the brown bear, wolf, boar, chamois and deer.

The mountains are the source of the name of the Balkans (sometimes considered as a distinct peninsula or region). In Bulgarian and Serbian the mountains are also known as Стара планина Stara planina (pronounced in Bulgarian as [ˈstarɐ pɫɐniˈna] and in Serbian as [stâːraː planǐna]), a term whose literal meaning is 'old mountain'.

It is believed^{[by whom?]} the name was brought to the region in the 7th century by Bulgars^{[citation needed]} who applied it to the area, as a part of the First Bulgarian Empire.^{[citation needed]} In Bulgarian, the archaic word balkan (балкан) was borrowed from Turkic and means "mountain". It may have ultimately derived from the Persian bālkāneh or bālākhāna, meaning "high, above, or proud house." The name is still preserved in Central Asia with the Balkan Daglary (Balkan Mountains) and the Balkan Province of Turkmenistan.

In Antiquity and the Middle Ages the mountains were known by their Thracian name: the Haemus. Scholars consider that the name Haemus (Αἷμος) is derived from a Thracian word *saimon, 'mountain ridge'. The name of the place where the range meets the Black Sea, Cape Emine, is derived from Aemon.

There are two different folk etymologies for the name Haemus, derived from ancient Greek mythology. One suggests that the name 'Haemus' comes from the Greek word "haima" (αἵμα), meaning "blood," based on the myth of the battle between Zeus and the monster/titan Typhon. The other attributes the name to King Haemus. See the Mythology section below for more details.

Other names used to refer to the mountains in different time periods include Aemon, Haemimons, Hem, Emus, the Slavonic Matorni gori and the Turkish Kocabalkan.
