The Brandenburg Gate is a monument in Berlin erected in the late 1700s. When the Berlin Wall went up in 1961, the Gate was on the East German side near the Wall, and largely off limits. When the Wall came down in 1989, the Brandenburg Gate became a symbol of freedom and unity.

I think that's just one example of how when things seem impossible, there's always a possibility for hope and change when people are willing to fight for it."
