I was looking at the chimneys earlier and estimated they are at least 60 stories which depending on the height of each story would be at minimum 720 feet, but I did not think they were really that tall. I just googled it and they are in fact 980' tall, among the tallest chimneys in the world. They are reinforced concrete and must have tested the men who built them. I wonder if they placed the concrete with helocopeters?

The tops are lost in the clouds at the moment.
