One of the major art commissions at the Olympic Park, ‘History Trees’ fuses nature and art with trees bedecked with giant metal rings. The ten semi-mature trees — each a different species, from Silver Lime to English Oak — will stand at the entrances to the Olympic Park. Three have already arrived at their new home, while the remaining seven will be planted after the Games. Each tree will bear a bronze or stainless steel ring weighing up to 500kg in its branches, engraved with text detailing history from the location. The artists behind the work, Ackroyd and Harvey, said the artwork will “transform as the seasons change, reflecting the evolving nature of the Olympic Park.”
