A medieval church tower in the heart of London's financial district is standing on stilts 45 feet up in the air thanks to an "unprecedented feat of engineering".
700-year-old All Hallows Staining has been protected in this unusual way while excavation of a 36-storey skyscraper takes place at 50 Fenchurch Street.
The final construction will merge the office block's basement levels and the church tower, which is believed to date back to 1320 and is all that remains of the church. The historic building is believed to have survived the Great Fire of London in 1666 but collapsed five years later due to excessive burials around it.
Where the tower meets the skyscraper at ground level there will be a new green public space. The project is due for completion in 2028.
The tower is part of a major City of London building project and 125,000 tonnes of earth were removed in order to start building.
Construction workers are also having to operate around Lambe’s Chapel Crypt, a grade II listed building and also part of the site. The chapel is associated with William Lambe and the Clothworkers' Company and comes with a complex history, having been demolished and rebuilt in 1825.
Up until now All Saints has not been accessible to the public but once construction work has finished people will be able to visit it.
