1. FC Union Berlin

1. FC Union Berlin, founded in 1906, is a club deeply rooted in working-class East Berlin, Germany, competing in the Bundesliga and playing at the An der Alten Forsterei, one of the most atmospheric stadiums in European football, set within a forest in the Köpenick district. Known as the Eisernen, or the Iron Ones, Union Berlin became famous for their community spirit, most notably when fans volunteered to renovate their ground by hand. After decades in the lower divisions, the club earned historic promotion to the Bundesliga in 2019 and qualified for the UEFA Champions League in 2023. Their identity is built on togetherness, humility, and an underdog spirit that resonates far beyond Berlin's borders.
