Old and new photos show what has changed in Da Nang over the last two decades, from a small town to Viet Nam's third largest city.

This old photo shows what Da Nang looked like 20 years ago, with so many trees and no high-rise buildings.

An extraodinarily fast pace of growth and development has turned Da Nang into Viet Nam’s third largest city.

The east side of the Han River used to be underdeveloped.

Many skyscrapers have popped up.

The waterfront area was once occupied by small houses.

Now it is the administration hub.

These old houses along the Han River...

… have been pulled down to make room for Nguyen Tat Thanh Street

Tran Hung Dao Street used to be the home of local fishermen.

And this is the street now.
