The branding is being launched at today’s AEO (Association of Event Organisers) Conference at the Olympia Conference Centre. Its design incorporates elements of its ornate barrelled roofs of the Olympia Grand National.
As part of the rebrand, venue Olympia Two will be renamed Olympia Central.
The £30m redevelopment included the infilling of the atrium space on the first and second levels and a refurbishment of its Conference Centre facilities.
Nigel Nathan, group managing director of Earls Court and Olympia, said: "The recent redevelopments at the venue have transformed Olympia, creating more versatile spaces that complement our first-class customer service.
"We enter 2013 by re-launching the space with the unveiling of a new, contemporary brand identity that will accompany us on our journey into the next 125 years."
Sister venue Earls Court is also launching a new-look logo.
