Around 20,000 people attended the event at the Titanic Slipways in Belfast, the area where Titanic was built and first launched.
The 45 minute evening show involved more than 500 people and took place against the backdrop of the new Titanic Belfast exhbition centre.
It saw a central character, Grace, on a journey visiting historical figures from Northern Ireland, including Harland and Wolff who built the Titanic, Samson and Goliath and Cave Hill’s sleeping giant - said to be the inspiration behind Jonathan Swift’s Gulliver.
Land of Giants was organised by a consortium including Belfast City Council, Beat Carnival, Belfast Community Circus and Young at Art.
It was part of the London 2012 festival, the cultimating 12-week programme of arts in the Cultural Olympiad which celebrates the London 2012 Olympics.
Ruth Mackenzie, director of Cultural Olympiad, said: "Well done Belfast for the stunning images of the London 2012 Festival – these will go round the world and be an amazing legacy for Belfast."
Cian Smyth, London 2012 creative programmer at the Arts Council of Northern Ireland, said: "This is a new and exciting era for outdoor arts events in Northern Ireland. An event of this scale and calibre, involving so many people, has never been staged here before and sets a high standard for the sector. The development of our arts performance and events sectors as a result of the show can’t be underestimated."
