For nearly 30 years during the Cold War, the Brandenburg Gate was a symbol of what people could not have. When the Berlin Wall was built in 1961, the gate was trapped in the death strip of no-man's land, unreachable by citizens of either East or West Berlin. It was here, in 1987, that United States President Ronald Reagan stood and famously challenged, 'Mr. Gorbachev, tear down this wall!' When the wall finally did fall in 1989, over 100,000 people gathered right where you are standing to celebrate a reunified Germany. For a practical tip, if the crowds today feel overwhelming, look toward the northern wing of the gate—the side to your right if you are facing Tiergarten. Inside, you will find the Room of Silence. Opened in 1994 and modeled after a meditation room at the United Nations in New York, it is a neutral, non-denominational sanctuary designed for reflection amidst the city’s bustle. Admission is free, and it offers a rare moment of absolute quiet at the city's loudest historical intersection.
