National Westminster Bank (NatWest) Tower, Old Broad Street, City of London, seen from Undershaft

NOTES: The National Westminster Bank (NatWest) Tower remained the tallest building in the City of London until the erection of the nearby Heron Tower in 2009. Badly damaged in the Bishopsgate bombing of 1993, the tower was subsequently entirely reclad and refurbished internally and renamed Tower 42.
