The Cologne Perfume Museum is located near the Cologne City Hall. From the Cologne Cathedral, walk along the shopping street to one intersection to another alley. It is easy to find with GPS. There are two floors, one floor is for perfume, and the second floor is a museum. The first bottle of cologne is more famous here and the taste is fresher. There are many different sizes to buy, and it is good to pack it for gift giving. There is also a constellation perfume, but the taste is generally the same.
