Munich is the capital city of Bavaria, Germany. It is located on the River Isar north of the Bavarian Alps. Munich is the third largest city in Germany, behind Berlin and Hamburg. About 1.35 million people live within the city limits. Munich hosted the 1972 Summer Olympics. The city's motto is "Munchen mag Dich" (Munich likes you). Before 2006, it was "Weltstadt mit Herz" (Cosmopolitan city with a heart). Its native name, Munchen, is derived from the Old High German Munichen, meaning "by the monks' place". The city's name derives from the monks of the Benedictine order who founded the city; hence the monk depicted on the city's coat of arms. Black and gold—the colours of the Holy Roman Empire—have been the city's official colours since the time of Ludwig the Bavarian. Modern Munich is a financial and publishing hub, and a frequently top-ranked destination for migration and expatriate location in livability rankings.
