SHEEP DRIVE Heard the one about the farmer, the shepherds and the five dogs herding 60 sheep through the city? London's changed just a bit since the woolly ones regularly walked the streets to market, so to contrast old and new uses of London's roads, the animals will be driven between Borough and Smithfield markets via the ultramodern Millennium Bridge that spans the Thames. Norman Foster, the bridge's architect, plans to lead the way.
TALKS Head to Southwark Cathedral for the "sermon" by Renzo Piano, co-architect of Paris' Pompidou Center, on the grand design for his London Bridge Tower. Dubbed the "Shard of Glass," it should stand as Europe's tallest building when completed in 2010. Then drop in at the Barbican to hear Rem Koolhaas, a fierce critic of skyscrapers, at the Big Debate on London's soaring skyline.
PASSEGGIATA Armed with a bit more knowledge, it'll be time to hit the streets. On the Passeggiata (Italian for a walk), you'll take in architectural gems, temporary installations and exhibitions on a stroll from south to north London. All that, and refreshments, from coffee and pastries near Borough market to dessert at St. John's Square. Thanks to the architects, you'll have seen the city from a whole new angle. londonbiennale.org.uk
