The Dom of Cologne, a gothic masterpiece, took 6 (!) centuries to be completed. During all this time, the builders stuck to the original plans. The place where the cathedral was built has been a place for catholic worship since the 4th century.
The Dom is the first building you see when coming out of the train station. And it is an impressive sight! I visited the cathedral a couple of times and even climbed the stairs to the top. A magnificent view over Cologne and its surroundings was the welcome reward! Well worth a visit!
Although the Dom itself is certainly a highlight in this city, we would love to recommend a visit to the Museum Ludwig as well. During wintertime the Christmass markets in Köln light up the city. And don’t miss a visit to the chocolate museum!
