Countdown has begun to the Royal opening of Terminal 2 by Her Majesty The Queen.

There are just three days to go to until Heathrow welcomes Queen Elizabeth II to the terminal named in her honour.

To mark the upcoming Royal opening here at getwestlondon we have trawled through the archives and found photos past and present of Terminal 2.

The Queen's Terminal as it is known had a soft opening on June 4, 2014, with the first of the Star Alliance carriers United Airlines operating its flights out of the new £2.5bn building.

The old Terminal 2, originally known as the Europa Building, was opened by The Queen in 1955, before being demolished after 54 years in service in 2009.

In the last five years the old terminal and control tower have been demolished, and the construction work and opening of the new building have resulted in what has been called "a mini T5."

Terminal 5 was opened by The Queen on March 18, 2008, now fast forward six years and another Royal opening will mark another milestone for the world's fifth busiest airport.
