Historical buildings in Berlin

There are pictures of the current German Parliament building (with painter), an art museum, and more beautiful buildings that I have no clue about.

This is Checkpoint Charlie (white small building)- the American military ran it while the wall was up and it remains as a tourist attaction - next to the Einstein Coffee House.

This is the Holocaust memorial in Berlin (grey slab picture). Underground is a list of the millions of Jews and others who were killed by name (see more at Wikipedia).
