The 75th anniversary of the Hiroshima bomb was a couple of days ago. The second bomb was dropped on Nagasaki 75 years ago today, on 9 August 1945 at 11:02.

I was in Nagasaki a couple of weeks ago and stopped at the hypocenter monument pictured above. The black monolith points up where at 500 meters the bomb exploded, killing a third (75,000 people) of the city and injuring another third. At least 182k deaths have been attributed to the bomb.

There are a number of displays at the hypocenter, including this heart-rending statue:

She looks out onto a plaza that is covered in chalk scribbles — like what you would see on an EKG readout. The lines cover the whole plaza, all leading towards the hypocenter. Here and there a small section has a chalk frame and a number.

Turns out this is an AR art installation by Shinpei Takeda. You download the app and point it at those special markers and you can hear the stories and see pictures of the aftermath. Take a look at this video to see a quick demonstration.

Further up the hill is the Nagasaki Peace Park, filled with statues made by local artists and gifted from countries around the world in sorrow and solidarity.

They call Hiroshima “The City of Monuments”, but Nagasaki has its fair share. On this 75th anniversary, spare a thought for the second and last city in all of human history to be the victim of an atomic weapon.
