Beauty does not always come at a price, but it does when it comes to lighting the world's most spectacular landmarks.
A new infographic has revealed just how much it costs to keep some of the planet's most famous landmarks lit.
The dazzling Las Vegas strip, whose countless neon signs burn brightly into the desert night, perhaps unsurprisingly costs a staggering £99million ($127million) a year to illuminate.
The thriftiest landmark when it comes to nighttime illumination is Buckingham Palace. The Queen's official London residence costs just £9,443 to light every year, although the building is only lit until the early hours of the morning.
The infographic, compiled by Lyco, reveals the number of luminaires used in a building's lighting scheme, how much energy is required and the costs per year to light the structure.
After the Las Vegas strip the second most expensive landmark to illuminate is the world's tallest building, the Burj Khalifa in Dubai.
In order to light the 2,723ft residential tower, it costs £300,468 every year to power 70,000 LED lights.
It requires 20,000 lights to illuminate the iconic Eiffel Tower in Paris and 68,000 luminaires to light the Empire State Building in New York. It costs £183,960 a year to light America's most famous skyscraper, which sometimes changes colour in response to national occasions and international events.
Sydney Opera House, which often features entertaining light shows on the building's famous sails, is brought to life via 17 projectors, which collectively cost £39,092 every year to power. It also costs £97,000 to light the impressive Montjuic Fountains of Barcelona.
'Recent technological advances in lighting, including changeable LED coloured lighting means that the use of lights to enhance public places has exploded in the last few years,' Charles Barnett, managing director of Lyco commented.
'Talented lighting designers are taking advantage of this new technology and are using light to make dramatic and spectacular statements at some of the world's best loved landmarks.'
