On April 24th 1993, the Provisional IRA exploded a large truck bomb in the Bishopgate area of the City of London. The bomb extensively damaged the NatWest Tower and many other buildings in the vicinity. The tower required extensive repairs and the NatWest relinquished ownership.
The tower was then known for a time as the International Financial Centre. The current name comes from its 42 habitable storeys.
