Heathrow Terminal 2, also known as The Queen's Terminal, is an airport terminal at Heathrow Airport, the main airport serving London, United Kingdom. The new development was originally named Heathrow East Terminal, and occupies the sites where the previous Terminal 2 and the Queens Building stood. It was designed by Luis Vidal + Architects and opened on 4 June 2014. The original Terminal 2 opened in 1955 as the first terminal at Heathrow, named the Europa Building. When Terminal 1 was built in May 1969, the Europa Building was renamed Terminal 2 to not cause any confusion.
