Little Boy, the atomic bomb was dropped on Hiroshima by US exactly 75 years ago. Three days later, a second bomb, Fat Man, was dropped on Nagasaki.

The device that exploded over Hiroshima destroyed about two-thirds of the city’s structures in a blinding flash of light. At the time, Hiroshima’s population was approximately 300,000. The atomic bomb immediately killed 80,000 and injured 35,000 more. By the end of 1945, 60,000 more people had died as a result of the blast.

Today, Hiroshima and Nagasaki are a prosperous manufacturing hub with a population of over 1.1 million.

Here’s what the city looks like today and the lingering effects of the bombing:

The gutted Hiroshima Prefectural Industrial Promotion Hall – now known as the A-Bomb Dome or the Hiroshima Peace Memorial – after the bombing on 6 August 1945, and the same location near Aioi Bridge in 2015.

The etched outline of a passerby that was imprinted on the Yorozuyo Bridge after the heat of the bomb. This was 860 metres from the centre of the blast; the asphalt was scorched everywhere except the light area, which was shielded by their body. Today, the bridge has been tiled over.

Residents walk near Aioi Bridge in Hiroshima, October 1945, and the bridge today.

People walk past the A-Bomb Dome on the Aioi Bridge. Today, cyclists cross the bridge.
