Cologne Lowland (German: Kölner Bucht) is a region in North Rhine-Westphalia, Germany, centered around the cities of Cologne and Bonn on the river Rhine. With around 3 million inhabitants, it is one of Germany's most populated areas, and it houses many institutions of national and global stature, including world-renowned universities, federal institutions and business headquarters. Thanks to that and its excellent connectiveness, it sees one of Germany's highest numbers of visitors, both arriving in specific interests and casual tourists.
