Hanoi: Vietnam's Historic Capital City

Geography & Layout

Hanoi spans 3,358.6 km² in northern Vietnam, positioned at the confluence of the Red River and Tô Lịch River. The city's topography is predominantly flat, characteristic of the Red River Delta region. Major natural features include Hoàn Kiếm Lake and West Lake, which define the urban landscape and serve as cultural anchors. The city is organized into 12 districts and 1 town, with Old Quarter serving as the historic commercial center. French colonial urban planning left a distinctive imprint, evident in wide boulevards, lake-facing villas, and tree-lined streets that contrast with the dense residential neighborhoods. The tropical monsoon climate influences seasonal flooding patterns in lower-lying areas.
