When was the Berlin Wall demolished?

The correct answer is 1989. The Berlin Wall, a guarded concrete barrier that physically and ideologically divided Berlin from 1961 to 1989, was effectively demolished on November 9, 1989. Its fall symbolized the end of the Cold War and paved the way for German reunification.

• 1987 is incorrect; while there were calls for its removal, the wall remained standing.
• 1902 is incorrect; the wall was built much later in 1961.
• 1994 is incorrect; the wall had already been dismantled years prior.
