Our Dynamic Earth, Scotland's MIllennium project, has re-appointed the Manchester-based advertising agency Barrington Johnson Lorains to handle its above-the-line account.
1576 and The Leith Agency lost out in the pitch for the account, which has been held by BJL since the attraction opened its doors around three years ago.
The media planning and buying account which is held by CIA Scotland was not under review.
Deborah Lidgett, PR manager for Our Dynamic Earth, said: "BJL were simply the best on the day. We liked what they did creatively."
