Yerevan (Երեւան) is the capital of the Republic of Armenia and one of the three hubs of the South Caucasus. It's home to over a million people - the largest Armenian community in the world.
Even though the history of Yerevan dates back to the Erebuni fortress, making it at least 2800 years old, little remains of what was small settlement saving the excavations at Hrazdan river gorge, Erebuni, Karmir Berd and Avan. These sites have been excavated, and the artefacts found are in museums today. Being on a strategically important place Yerevan was a constant war stage for rival Ottoman, Persian and Russian Empires. It has been repeatedly ruined by those wars or natural disasters (e.g. an earthquake in 17th century almost entirely destroyed the town). Few buildings of the old Erivan survived to the present-day Yerevan. At the time of Armenia's independence in 1918, when Yerevan was made the capital of an independent Armenia, Yerevan was a town of just 20,000. Large scale construction began, which took a more holistic approach under the new city plan laid out by Alexander Tamanyan. The plan involved the demolition of much of what existed, in favour of concentric circles, parks, and taller structures. He planned for Yerevan to become a metropolis of 200,000 people.
