Cologne

Cologne is the fourth-most populous city of Germany and the largest city of the German state of North Rhine-Westphalia with over 1.0 million inhabitants in the city proper and over 3.1 million people in the Cologne Bonn urban region. Cologne is also part of the Rhine-Ruhr metropolitan region, the second biggest metropolitan region by GDP in the European Union. Centred on the left bank of the Rhine, Cologne is located on the River Rhine (Lower Rhine), about 35 kilometres (22 mi) southeast of the North Rhine-Westphalia state capital Düsseldorf and 22 kilometres (14 mi) northwest of Bonn, the former capital of West Germany. The city's medieval Cologne Cathedral (Kölner Dom) was the world's tallest building from 1880 to 1890 and is today the third-tallest church and tallest cathedral in the world. It was constructed to house the Shrine of the Three Kings and is a globally recognized landmark and one of the most visited sights and pilgrimage destinations in Europe. The cityscape is further shaped by the Twelve Romanesque churches of Cologne. Cologne is famous for Eau de Cologne, which has been produced in the city since 1709; "cologne" has since come to be a generic term. Cologne was founded in Germanic Ubii territory in the 1st century AD as the Roman Colonia Agrippina, hence its name.
