Following the extraordinary success of the first London Biennale in 2004, this year's event promises to be even bigger, better and more colourful. The show, which kicks off tomorrow (16 June), will boast the longest architecture exhibition in the world - a 5km route from King's Cross to Borough Market - and is likely to pull in more than 100,000 visitors. An already sold-out 'sermon' by Renzo Piano at Southwark Cathedral is just one of the highlights of the nine day festival (visit www. londonbiennale. org. uk for a list of all 170 talks, walks, shows and exhibitions). Here are some of the other must-see events.
SHEEP DRIVE 17 June, 10am, between Borough Market and Smithfield Market Don't believe those rumour-mongers: Norman Foster has not had a change of heart. On Saturday you too can see the Stirling Prizewinning architect herd 60 sheep across his Millennium Bridge. The event is not just a shameless attempt to raise the Biennale's profile, it apparently also ties in with this year's theme of 'Change' and harks back to when farmers used to drive sheep across the Thames to Smithfield Market.
SUB URBAN 16-23 June, 11am-6pm, Hayward's Place, EC1R 0EU This exhibition about the world below the capital is free to enter and features previously unseen photographs of secret subterranean locations across London. For a full preview, see Critic's Choice (page 55). Or find out more about how the archaeology under London has shaped today's city on a guided tour: The Below & Above walks cost £7/£5 and can be booked through kpflude@chr. org. uk, or call 020 88063742.
ARCHIOSK 17 June, Smithfield Market Roll up, roll up. For only £15 you can have your problematic plans looked at by former-Alsop hotshots David West and Christophe Egret (of Studio Egret West) and engineers Arup. All money raised by the Archiosk architectural surgery will go to charity. Meanwhile, on a grander scale, the 'Big London Brainstorm' exhibition at Smithfield house, Lindsey Street EC1, offers up a glimpse of how the capital could look if architects were given a totally free reign. Organised by journalist Tom Dyckhoff, the event runs all week.
