A Dubai resort hopes to build a giant replica of the moon on top of a skyscraper costing over £4billion.
Canadian entrepreneur Michael Henderson plans to erect a 274-metre (900ft) sphere on top of a 30 metre (100ft) building in the United Arab Emirates city state.
It is already home to the world's tallest building, among other architectural wonders.
The project - called MOON - would essentially provide the experience of visiting the space satellite without having to leave Earth.
And hopes to attract over 2.5million guests annually.
It is estimated that the attraction could bring in over £1.5billion in a single year.
The scheme - likely to cost £4.28 billion - is being funded by Moon World Resorts Inc, of which Henderson is the co-founder.
He said: "We have the biggest 'brand' in the world.
"Eight billion people know our brand, and we haven’t even started yet."
The project would include a resort inside the spherical structure, complete with a 4,000-room hotel, an arena with 10,000 capacity, a nightclub and wellness centre.
A 'lunar colony', meanwhile, would allow guests to experience what it would actually feel like to walk on the moon.
The structure would be placed on a pedestal-like building and would glow at night as a full, half or crescent moon.
Earlier this month, Henderson talked about his plans at the Arabian Travel Market in Dubai.
In a previous statement, he and co-founder Sandra G Matthews said Moon Dubai will "significantly impact every aspect of the UAE’s economy, including tourism".
Also targeted are "transportation, commercial and residential real estate, infrastructure, financial services, aviation and space, energy, MICE, agriculture, technology and of course education".
They continued: "[It] will be the largest and most successful modern-day tourism project in the Middle East and North Africa (MENA) region, doubling annual tourism visitations to Dubai based on its global appeal, brand awareness and unique multiple integrated offerings."
The city already boasts the UAE’s space centre, which has sent a probe to Mars and unsuccessfully tried to put a rover on the moon.
Henderson's project would be a step further than the MSG Sphere, a $2.3billion dome blanketed by LED screens, due to launch in Las Vegas this year.
Plans to build another MSG Sphere in London were scrapped after locals protested about the light pollution and disruption it would cause.
Henderson responded: "It’s hard to please everybody.
"You might need dark curtains."
