Worldwide: City To City

Barcelona

Mounted in honour of the birth centenary last year of Rene Magritte, this major retrospective features 80 oil paintings, 10 drawings and 55 photos. All produced between 1925 and 1957, they have been organised into five sections reflecting recurrent themes in Magritte's work: Narrative and Mystery, Chance Encounters, Metamorphosis, Mechanisms of Language and The-picture-within-a-picture. Perhaps best known for his 1928-9 oil on canvas The Treachery of Images, in which the phrase "Ceci n'est pas une pipe" is etched beneath a pipe, the Belgian began his career as a commercial artist before addressing concepts of representation and definition in his Surrealist paintings. The exhibition explores how he transformed his everyday surroundings into a fantastic and sometimes disturbing world on canvas.

Cologne

Tomorrow is your last chance this year to visit the Cologne Furniture Fair - and your first to see British designer Matthew Hilton's new injection- moulded plastic chair - the Wait - for the German company Authentics. For over 50 years the fair has been attracting a worldwide audience to its display of classic and avant-garde furniture design. This year, there's a new sector on domestic lighting.

Vienna

Don't mothball that Christmas party dress just yet: the season of the Viennese ball is upon us. From now until the end of February, more than 200 balls will be taking place at prestigious locations throughout the city of the waltz. Although long dresses and tuxedos aren't de rigueur for the majority of the dances - including the Flower Ball, the Huntsmen's Ball and the Philharmonic Ball - swanky outfits are required for the most famous, the Opera Ball (11 Feb). And if you can find Asch75,000 for a box at the Opera, you may have a perfect view of Baby Spice, Emma Bunting (below left), waltzing away in the arms of billionaire Austrian businessman Dicky Lugner, who has invited the singer to be his dancing partner.

Osterreichischer Bundes-theaterverband, Opera Ball Office, 1 Goethegasse, Vienna, Austria (00 43 1 211140) to 28 Feb, tickets for the Opera Ball start at Asch150, plus Asch2,700 entrance fee
