A medieval church has been lifted into the air and suspended on stilts in an extraordinary engineering feat in central London , while construction of a 36-storey skyscraper takes place around it.

The Tower of All Hallows Staining, a 700-year-old structure, is now sitting on specially designed supports after engineers removed 125,000 tonnes of earth from beneath it.

The remarkable achievement was accomplished through “high stakes mathematics” rather than divine intervention.

Engineers measured precise specifications for the special stilts, which were slowly moved into place as the massive amount of earth beneath the historic structure was excavated.

A special “bottoming out” ceremony was held to celebrate the engineering milestone, highlighting the astonishing scale of the project at
