Xstrata at Kew

Tomorrow a new architectural feature opens to the public in Kew Gardens: the Xstrata Walkway designed by Marks Barfield Architects, the firm that created the London Eye. The new walkway is 656ft long (200 of those Euro metre thingies) and 59ft (18m thingies) above the ground and allows visitors with a head for heights to stroll among a canopy of sweet chestnuts, limes and deciduous oaks. As I get vertigo replacing a light bulb, I'll give it a miss; but for wannabe Tarzans it looks great.
