The Altstadt (old town) is a city district of Frankfurt am Main, Germany.
Located on the northern Main river bank, it contains many of Frankfurt's most important sights, including the Römerberg ("Roman Mountain") plaza with the famed Römer city hall, the Old St Nicholas Church (Alte Nikolaikirche), and many other middle-age style buildings.
Frankfurt’s old town was once a massive centre of trade and commerce, with the Römer – today’s city hall – having been an indoor marketplace for Roman merchants.
Many centuries ago, Frankfurt was home to Germany’s largest timberframe old town. It was in fact known to be the most beautiful example of Gothic-styled, half-timbered architecture in the entire country.
Germany’s largest mediaeval old town was once also the home of famous poets, intellectuals and composers, such as Johann Wolfgang von Goethe, Arthur Schopenhauer, Clemens Brentano, Ludwig Börne and Georg Philipp Telemann, just to name a few.
