Melbourne has lit up for its annual White Night Festival.

Now in its fourth year, the all-night celebration lasted from Saturday 7pm to Sunday 7am with half a million people gathering in the city to celebrate its culture and creativity.

The 12-hour light festival transformed some of Melbourne’s iconic landmarks into light installations and also saw a number of exhibitions, street performances and interactive events take place in the city’s streets.

The idea for White Night (Nuit Blanche) originally came about in Paris in 2002 as an arts and culture festival. Since then, more than 20 cities around the world have held their own White Night event such as Rome, Helsinki, and Toronto with the first one in Melbourne taking place in 2013 drawing over 300,000 visitors.

The Victorian Government is seeking a regional centre to co-host the overnight event next year which brought in close to $17 million last year.

“Regional centres like Geelong and Ballarat and Bendigo and other centres are so important to our economy and we want to make sure that we grow the economy in regional Victoria through these events,” minister for tourism and major events John Eren told the ABC.

Here’s a look at this year’s White Night:
