The famous wall that marked the division of East and West Berlin was the Berlin Wall, constructed in 1961. It served as a physical and ideological barrier between the Eastern Bloc, led by the Soviet Union, and the Western democratic nations during the Cold War. The wall separated families, friends, and communities for 28 years, representing the broader struggle between communism and capitalism. The Berlin Wall became a symbol of oppression, confinement, and the stark division in Europe. Its fall in 1989 marked a significant turning point, heralding the end of the Cold War and leading to the reunification of Germany.
