"This free indoor/outdoor museum and memorial is the best place to learn how the Berlin Wall sprung up, practically overnight, what life was like in the former East German state, and the heroic (and heartbreaking) attempts people made to reunite with their families. As you walk along this one-mile stretch of Bernauer Strasse, an open-air exhibit features photographs and signs detailing the stories on either side of the barrier. There’s also a preserved piece of the original border wall and a watchtower, as well as an indoor visitor center with exhibits chronicling the political and historical events surrounding the city’s division." - Jennifer Ceaser
