One of the world's most famous and tallest skyscrapers - the Empire State Building in New York - is getting taller, according to a report in the New York Times.
The article, in Monday's edition, claims that the 102-storey structure now stands 103 storeys high, after a security guard patrolling the upper floors noticed a new stairway on what he thought was the top floor. A closer inspection revealed a previously-unknown set of office suites which had appeared out of thin air.
For more than forty years, since its creation in 1931 until the World Trade Centre was built in 1971, the Empire State Building was the tallest building in the world.
After the WTC was destroyed by terrorists in 2001, the ESB then became the tallest building in NYC.
The building was made famous in 1938, when an enormous giant monkey scaled its heights before sadly falling to its death on the streets below.
Architectural engineers have claimed it is entirely possible for a building to grow taller, and say they expect the ESB to get even taller in the coming months as the US economy begins its slow recovery.
