Hanover's New Town Hall is an imposing building that opened in 1913 after almost 12 years of construction. It's located near what was once the historic city center, within Masch park. It was built during the era of Kaiser Wilhelm II by the architects Hermann Eggert and Gustav Halmhuber. Rumor has it that the construction cost 10 million marks, paid for by the Kaiser himself in cash. In the lobby, there are four models that reflect different eras of Hanover: in the Middle Ages, the pre-war era, post-war, and today. To climb the dome, you have to pay an entry fee, but it doesn't cost much and it is certainly worth it.
