nice thread.
I think there are too many buildings to be mentioned for Berlin alone.
This is one exmple though since its close to my house:
This used to be the Karstadt shopping mall that was built in 1929 and it survived the countless bombing raids and the Soviet artillery fire.
yet during the Battle of Berlin it was blown up by retreating SS-units.
the building used to be 71m high, had 9 levels and 72.000 square meters for shopping.
It also had its own underground station which still exists today.
It was fitted with atleast 2 automatic escalators per floor and many lifts.
and all floors were fitted with water sprinkler systems in case a fire would break out.
It wasnt the biggest pre-war shopping centre in Berlin though.
Ill post some more later.

the station survived the war:
nowadays it looks like this:
