The Victoria Tower is the square tower at the south-west end of the Palace of Westminster in London, facing south and west onto Black Rod's Garden and Old Palace Yard. Prior to being renamed in 1897 in honour of Queen Victoria during her Diamond Jubilee, it was known as the "King's Tower". At 98.5 metres (323 ft), it is slightly taller than the more famous Elizabeth Tower (formerly known as the Clock Tower and popularly known as 'Big Ben') at the north end of the Palace (96.3 metres (316 ft)). It houses the Parliamentary Archives in archive conditions meeting the BS 5454 standard, on 12 floors.
