Visiting Checkpoint Charlie was more entertaining than interesting. Less information about the walls and in the museums than any other historical site. The actors there are dressed like soldiers back then and ready to take pictures with people for a small fee.
A busy area filled with small museums and tourist shops selling souvenirs and stuff. I didn't see Checkpoint Charlie as a historical site because of the the fake soldiers standing here hired to take pictures with tourists for a small price. The checkpoint is interesting to see but not a must do in Berlin.
