janl, Learned loads about lime quarrying and cement production today. The Brandenburg Gate’s materials came from here (and most everything else in Berlin you see today).
In the tunnels under the hill in pic #4 on the far right, the Nazi government hid the national science library from allied bombing and the GDR government had its emergency bunkers there.
Limestone monoliths across earth ages.
