The MAC in Belfast is celebrating five years this week by encouraging its visitors to share their favourite moments at the arts venue on social media.
Over 1.5 million people from all over the world have visited the site since it opened in April 2012.
Chief Executive, Anne McReynolds, said this figure was far beyond what had initially been predicted.
She added: “The last five years have been a whirlwind of activity and it is important now that we take stock of what has been achieved.
"Along with the high-profile exhibitions and events like David Hockney, L.S. Lowry, Beckett and Cabaret, we have also created a new international art competition, MAC International, which has placed Belfast on the global arts scene."
She added: "We celebrate our 5th anniversary by looking to the next five years and imagining what might be possible. With the right support, the MAC will continue to symbolise all that is good about our city and Northern Ireland for years to come.”
The MAC is supported by the Arts Council of Northern Ireland.
Chief Executive, Roisin McDonough, said:“The Arts Council is delighted to have played our part as a significant funder and the MAC is a testament to the ability of public funding to transform our economy and generate positive creative energy within our society."
Since its inception, the MAC was shortlisted for the prestigious Museum of the Year award in 2015, one of the youngest organisations ever to have made the shortlist.
To celebrate five years of The MAC, visitors past and present are being encouraged to record their favourite #myMAC moments through Twitter, Facebook and Instagram.
