Oka starches over 1500 kilometers covering 250 000 square kilometers of basin area in Central Russia. It is listed among the world 100 longest rivers. Its banks are pined by numerous Russian historic towns, churches and monasteries, a vivid reminder of Oka’s role in the historic trade route connecting Scandinavia, Kievan Rus and Byzantine Empire. The scientist attributes the origins of the name Oka to the ancient Greek word «aqua» as yet another proof of the river’s historic significance to the region.
Oka’s importance stretches beyond its physical characteristics. For centuries the river had a profound impact on the local communities across Central Russia. Nowadays, it continues to define and shape the environment around it, equally bringing joys and challenges to the everyday way of life of the locals.
