With every step of this Hanoi city walk, starting at the Lotte high-rises (Ba Đình District), we will move closer to the streets of the Old Quarter. Notice how modern architecture and street layouts will begin to change to an ancient look and feel with every block we pass. Like a time machine carries us to the heart of the city - old, yellow, full of sidewalk vendors, packed with charming colonial architecture, Buddhist temples and pagodas - the Old Quarter.
