AGP Celebrates the 30th Anniversary of the Fall of the Berlin Wall at Birmingham’s Biergarten with German style food, beverages and networking. On 13 August 1961, work began on constructing the Berlin Wall. It stood as a symbol of a divided city and country, of terror and the Cold War. Overnight, it changed an entire nation. On 9 November 1989, Berlin was reunited. The Berlin Wall fell and the city was reunited. It was finally the end of the massive border complex that left Berlin divided into East and West for 28 years, tearing apart families, friends and neighbors. Today, Berlin is known as a place of freedom, opportunity and individuality.
