The element of destruction in architecture.

[Hollow_Man]

I'm doing a research for the element of destruction in architecture and I
would be very happy if somebody share his info about that topic.
In order to be more specific I want pictures or text regarding 2 topics.Any links for sites containing material concerning the topic will be welcome too.
1. building, churches or monuments that have been destroyed during wars or
other hostile situations and after their restoration the architects decided
to keep a part of the building as it is in order to remember what has
happened.
2. architects that design from the beginning buildings that look like they
are not finished or been destroyed by an earthquake and their walls are
bend, their windows are deformed and so on.

THANKS in advance.

There are many examples of large 19th century churches being damaged through man or by accident, and newer churches built inside the remains or alongside. Will have to look up a few.

Top of the list must be the Kaiser-Wilhelm-Gedächtniskirche in Berlin by Egon Eiermann (1904-1970):
