Father Christmas is abseiling down Erno Goldfinger’s iconic Balfron Tower block of flats in London’s East End.

He won’t be carrying his usual sack of toys, however—that stays locked away in his sleigh parked nearby.

But Santa is taking the 27-storey plunge today (Weds) in aid of three charities in east London.

Santa—otherwise known as Kevin Wright who is a director of Poplar Harca housing organisation which manages Balfron Tower—is making his leap of faith from the rooftop dressed as Father Christmas to raise money for St Joseph’s Hospice, Care for Causalities and Pollyanna’s Theatre School.

A winter wonderland of festivities including husky rides, Santa’s grotto, stalls, music, dancing and children’s games is being laid on from 4pm to 7pm outside Balfron Tower in St Leonards Road, Poplar, next to the A12 Blackwall Tunnel approach, to welcome Father Christmas making his historic abseil.

It’s the first time anyone has abseiled down the famous 1960s tower block—let alone Santa.
