However, most of the 2.6 square kilometre didn’t burn away of bombs but caught much later fire. The buildings were like old Londen build too close and narrow against eachother and the major water supply got hit by a bomb too. Thus the damage was less like the Second fire of Londen (to put it in perspective). Neither was the number of people killed (800/900) as large as hiroshima or dresden.
Nevertheless the impact was still heavy. Look for example here, here, here or here. Or try a images in a simple google search is obvious. I strongly recommend the “other times” documentary about the burnings too. I can also recommend the google map:
For more information of the raid and the fire, the mariniersmuseum in rotterdam has audio tapes and more background too.
Today, exactly 67 years ago and because of the year theme, the city memorate the events with a whole program. It will include a flower exhibition in the shape of flames, music, the opening of a walking route on the border lines of the burned down city centre. And similar to the light poles of New York memory will mothership flash the lines into the sky from 22.45 till 02.00 h. If you’re in town, take a look.
