A record number of people visited Dublin Zoo in 2012.
The final footfall figure for 2012 surpassed last year's 1m, reaching an all-time high of 1,029,417.
The increase of 2.5% confirms Dublin Zoo's status as the most popular family visitor attraction in Ireland with over 95% domestic visitors.
Director of Dublin Zoo Leo Oosterweghel said reaching 1m in 2011 was fantastic, but to do it again and add to that number is phenomenal.
He said: "We are delighted to say that the Zoo is more popular than ever.
"We are extremely proud to be in a position to say that after a decade of continuous development that Dublin Zoo is amongst the best Zoos in the world."
Last year saw the opening of the Asian Forest, and many new arrivals were welcomed, including a rare Eastern bongo calf, a tapir calf, two red panda cubs, two meerkat pups, two snowy owls and a sea lion pup.
For the first time ever, Dublin Zoo introduced two young Asian lionesses and a bull elephant, Upali, to the collection of animals.
