Stock Photo - Jul. 06, 1970 - Tower Succumbs to Persuasion. Hours of hammering with two one-ton steel balls swung, pendulum-like from a crane, failed yesterday to knock down the last of three 120ft high, 250-ton towers of a 300ft long granary at Nine Elms. The 36-year old building was being demolished to make way for the new market to replace Covent Garden. A workman inside a crane bucket had to cut six steel rods with an oxy-acetylene torch before the upper section of the last fragment of a local landmark on the south bank of the Thames collapsed in a cloud of dust. It has taken 11 weeks to pull down what was one of the first steel-reinforced concrete buildings to be built in London. (Credit Image: © Keystone Press Agency/Keystone USA via ZUMAPRESS.com)
