Great investment offering good returns.For many non-locals, megacity Cologne is associated with little more than its locally brewed "Kölsch" beer and the city's infamous carnival celebrations. But the cathedral city on the Rhine has much more to offer. Cologne is an economic hub and cultural metropolis with over 2000 years of history — so there is plenty to see and do. The cathedral, for example, is a famous landmark that offers breathtaking views of the city. The city's countless museums are home to prized collections. Cologne is also a key city for education, and is in fact the largest education and research centre in the Rhine-Ruhr metropolitan region. The botanical gardens and Cologne Zoo are great places to relax. The global city on the Rhine is also famous for its annual events, including the spectacular "Kölner Lichter" music and fireworks show and Germany's largest gay and lesbian parade.
