Visit Britain Promotes Devon and Cornwall
As part of a £4 million campaign to promote our regions, Visit Britain is using pictures of Devon and Cornwall.
There are 134 digital screens in Heathrow Airport's terminals, which will show the pictures of British landmarks.
A photo of Mevagissey fishing harbour is promoting Cornwall and Dartmouth Castle is Devon's offering.
Other places that are being used under the banner "This is Great Britain" include Glastonbury Tor, and a lighthouse on Llanddwyn Island in Wales.
Around 13 million passengers a year already use Heathrow and this partnership is designed to inspire passengers to explore further afield during their visit - or on future trips.
Malcolm Bell, Head of Visit Cornwall says "Cornwall has a high profile within the UK and a growing profile internationally. This welcome exposure will really assist us to promote Cornwall and place the recent extreme weather well behind us".
Sandie Dawe, Chief Executive of VisitBritain commented "Millions of visitors from overseas will see these spectacular images. Our aim is to inspire them to explore more of the country during their visits to Britain. We're really grateful to Heathrow for this wonderful gift of advertising space".
