Tower 42 was officially opened by Queen Elizebeth II in 1981.

It is the tallest building in the "City of London", and was the tallest building in the United Kingdom for 10 years, from 1980 to 1990, when One Canada Square became the tallest.

Formerly known as the Natwest Tower, the building's footprint is the shape of the National Westminister Bank logo.

While many books about London say that the building was the fist building in London to have 50 office floors this is not the case. The 50 floor figure includes the 5 plant floors and 3 basement floors.

Tower 42 is believed to be the tallest cantilever building in the world.

On Saturday 24th April 1993 the IRA exploded a truck bomb on Old Broad Street, killing 1 person and injuring 44.
Heavy damage was caused to both Tower 42 and 99 Bishopsgate, the damage to Tower 42 was repaired only 14 months after refurbishment started, with both buildings reopening in 1995.
