Give in to the minibus chaos to criss-cross your way through the city – for 100 Dram, and a loudly shouted “stop!” you’ll be dropped off at the Yerevan’s prized monuments. The pedestrian Northern Avenue takes you from the opera to the fountains at Republic Square. Imposing Soviet era buildings by day, elegant backdrop to a light and water show at night, the Republic Square is inevitably a must-see.
Enjoy the long summer nights in the pink city, as it’s called due to the pinkish stones of the buildings, at the café terraces, while snacking on lamehjun (Armenian-style pizza). Rebuilt to hide the scars of wars and natural disasters, most of Yerevan’s current attire is only a century old. Yerevan’s oldest heritage lies along the outskirts of the city where the Hrazdan River and deep gorge create a natural border.
