Language holiday in Cologne   Cologne is the oldest of Germany's big cities. More than 2000 years of history have left their mark on Cologne. And it is not only Cologne's famous cathedral - a gothic masterpiece - which bears testimony to times gone by. Numerous buildings, sculptures and gardens provide a vivid impression of the old Cologne.   Today Cologne is a modern, lively and cosmopolitan city: hub of trade fairs, university town and - with its many radio and television centres and over 350 film and TV production companies - the unquestionable media capital of Germany.     Furthermore, Cologne offers pure culture!   Opera, philharmonic orchestra, 40 museums, 42 theatres, 74 cinemas, concerts of every type, over 100 art galleries and innumerable antique dealers... In the evenings Cologne's vibrant nightlife will tempt you with its countless clubs and trendy bars.   Highlights of the calendar year are, above all, the wild days of revelry during the Cologne Carnival (February); the August Ringfest, one of the biggest music festivals in the world; and, of course, the yearly Gay Pride celebration on Christopher Street Day, with its colourful parade (July).   Discover and experience the old and new Cologne with your Tandem partner, with students from all over the world, with people who want to get to know each other, with us!
