Checkpoint Charlie

When Berlin was still a divided city, separated into East and West by the Wall,
few American tourists would have left the city  without having visitied
"Checkpoint Charlie."  Click here to find out what Checkpoint Charlie was or still is.
(Or read about Checkpoint Charlie "auf Deutsch.")
Write a brief explanation on your guide sheet.  
 
Not usually a "museum person" myself, I nearly missed this one:  
"Haus am Checkpoint Charlie."
It's the most interesting museum I've ever visited!  
Click on the link above to find out what kind of museum it is.   
On your guide sheet, make a note about what kind 
of displays you could expect to see here.
