The structure that marks the former divide between East and West Berlin during the Cold War is the Berlin Wall. Constructed in 1961, this formidable barrier symbolized the ideological divide between the capitalist West and the communist East. The wall physically separated families and communities for decades, and its presence became a powerful emblem of the Cold War tensions. The eventual fall of the Berlin Wall in 1989 not only marked the end of the division but also signified a turning point in the Cold War, leading to German reunification and broader changes across Europe.
