The Iskar ( Bulgarian : Искър , pronounced [ˈiskɐr] ; Latin : Oescus ) is a right tributary of the Danube . With a length of 368 km, it is the longest river that runs entirely within Bulgaria . Originating as three forks in Balkan 's highest mountain range Rila , the Iskar flows in a northern direction until its confluence with the Danube . As it flows northwards it fuels the largest artificial lake in the country, the Iskar Reservoir , forms the divide between the Vitosha and Plana Mountains in the west and the Sredna Gora mountain range in the east before entering the Sofia Valley , which contains the nation's capital Sofia . From there the Iskar runs through the Balkan Mountains , forming the spectacular 84 km long Iskar Gorge . As it crosses the mountains, its water course turns in a north-eastern direction at Lakatnik . North of the Balkan Mountains, the river crosses the Danubian Plain and finally flows into the Danube between the villages of Baykal and Gigen . Geologically, Iskar is the oldest river in the Balkan Peninsula.

In the 16th and 17th centuries, it grew into

812-594: The Danube in the early 580s AD. The Eastern Roman Empire , or Byzantium, was incapable of defending these territories at the time. With most Byzantine troops protecting the rich Asian provinces from Arab and Persian raids, even small and disorganised Slavic attacks caused much disruption throughout Moesia. The numerous Slavs gradually mixed with and assimilated the native population. The area remained under Byzantine control until 809 AD, when Krum captured Serdica and massacred some 6,000 soldiers and civilians. Sometime in

At the very beginning of the gorge to Rebrovo the inclination of the Iskar is only 0.75‰ and it flows slowly, forming meanders and even islets. However, the inclination soon increases to an average of 4.1‰ and the flow quickens, forming

1566-494: The Iskar takes its beginning at the village of German . As it enters the Sofia Valley (550 m) at the aforementioned village it turns northwards and forms a wide river bed. There the river flows through the easternmost suburbs of the national capital Sofia and is crossed over by the runway of Sofia International Airport . In the southern parts of the valley the Iskar has an inclination of 6.7‰ that decreases to 0.06‰ in

With a territory of 7 020 km², Sofia Province is the second-largest in Bulgaria. It also has the highest number of municipalities, 22, and borders nine other provinces as well as Serbia to the northwest. The lowest areas stand at 350 metres above sea level, whereas the highest rise above 2,900 metres, resulting in diverse terrain, soil and climatic factors. A temperate climate with cold winters, cool springs and mild summers hampers

1740-603: The areas north of Vitosha were inhabited by the Tilataei and the Treri . The Triballi were also known to have inhabited the region around Serdica . The Serdi , a Celtic tribe that appeared in place of the vanished Treri and Tilataei, were first mentioned in 29 BC. Roman General Marcus Licinius Crassus began his campaign against the Triballi in that year, and in 27 BC his troops captured Serdica. Felix Philipp Kanitz ,

Its high annual influx of tourists has given a boost to the local property market and has drawn foreign investment in hospitality and recreation. Samokov Samokov ( Bulgarian : Самоков [ˈsamokof] )

1914-490: The first person to study the Iskar Gorge area thoroughly, identified eight Roman castella , which he considered proof of the great strategic importance the Romans placed on the gorge. The road passing through it connected Roman lands from Thessaloniki all the way to Dacia . However, up until modern times, the gorge was poorly accessible because of its rugged terrain. As a result, the inhabitants were partially isolated from

In 1565–1566, Samokov had to produce and deliver to Belgrade 20,000 horseshoes and 30,000 nails . Samokov also produced anchors and other materials for the shipyards of the Bulgarian Black Sea Coast , particularly Pomorie. As the logging industry was also well developed, in 1573

It flows through a deep valley for 18 km until its confluence with Cherni Iskar downstream of

2204-452: The lower Iskar valley are higher and steeper than the left. In the past, the riverbed was carved into an alluvial bottom and due to the small inclination the river used to form meanders with swampy banks. Nowadays the Iskar flows in a corrected riverbed during the last about 17 km until it reaches the Danube. The riverbeds of some of its tributaries such as Blato, Stari Iskar and Kakach Kriva river have also been adjusted. The confluence with

There it fills the Pasarel Reservoir and Lake Pancharevo . The middle course of

The earliest evidence of a mass settlement dates back to Thracian times, including tumuli (burial mounds) which remain poorly studied. According to Thucydides ,

Some of the population of Moesia thus found the Iskar river area an appealing safe haven later in the 5th century , when the province was threatened by Hunnic and Gothic raids (see also Collapse of the Western Roman Empire in 476 ).

The waters of

2958-441: The skirts of Rila mountain, and the mitigating proximity to the continental mediterranean climate zone, are both strong factors in forming the climate. Summers vary from very warm, sunny and dry to warm and humid, while winter can be relatively mild and wet with much snowfall, but also colder and drier. Spring is often cool and wet, while in autumn there can be numerous sunny, warm days. Samokov Knoll on Livingston Island in
