Munich is the capital city of Bavaria (Bayern), Germany. It is located on the River Isar north of the Bavarian Alps. It is the third largest city in Germany, after Berlin and Hamburg. There are about 1.35 million people living within city limits, while the Munich Metropolitan Area (including the urban areas of Augsburg, Ingolstadt, Rosenheim and Landshut) is home to over 5 million people.The city is a major centre of art, advanced technologies, finance, publishing, culture, innovation, education, business and tourism in Germany and Europe, and enjoys a very high standard and quality of living. Munich's cultural scene is second to none in Germany, with the museums even considered by some to outrank Berlin in quality. Many travelers to Munich are absolutely stunned by the quality of the architecture. Although it was heavily damaged by allied bombing during World War II, many of its historic buildings have been rebuilt and the city center appears mostly as it did in the late 1800s including its largest church, the Frauenkirche, and the famous city hall (Neues Rathaus).
