Thousands of people participated in the lighting ceremony, one of the traditional Christmas attractions in the city. This year's theme "A Christmas of Lights", takes visitors through the history of light, starting with the glow of the stars and culminating with Christmas lights.
Crowds flocked to the waterfront to watch as the 542 ton and 85 metre high structure was lit up by a dazzling display of multicoloured fireworks.
The tree itself contains 3.1 million micro bulbs, 2,150 strobe effects and 100 LED reflectors, which enable the record-beating tree to change colour and display different designs.
Each year there is a new theme, represented by the tree’s lights, and 'A Christmas Light' was chosen for 2014 - celebrating the importance of light in people's lives, symbolised by the sun, moon and stars.
The tree, which will be lit every night until January 6, has been officially certified by Guinness World Records as the largest of its kind in the world.
