In ye olde London when the weather got this cold and the Thames froze over, the city would have a frost fair. They would crack out the food and booze, play a few games and go for a skate. Sadly this tradition died out many moons ago. Probably because it’s completely mental.This year it’s the 200th anniversary of the last frost fair, and what better way to mark the occasion than by bringing it back to life. Recreating the Thames in 1814, ‘Frost Fair 200’ will be held at Broadgate today (5-10pm) with market stalls selling old-fashioned food, treats and souvenirs. There will be street games, free ice-skating, stilt walkers, live performances, and although it’s not very 1814, BAR BBQ will be there serving up some hot rink-side food and the Corney and Barrow cider chalet will be ladling out hot cider.
