With a Diameter of 271 Meters and a Height of 312 Meters, the Largest Spherical Building in the World Promises a Resort with 4,000 Rooms, Simulated Lunar Surface, and a Competition Among 10 Countries to Host the Megaproject
The Moon Project aims to bring to life the largest spherical building in the world, a moon-shaped structure that seeks to deliver the experience of space tourism directly to Earth. The idea is to recreate the feeling of being on the lunar surface within a giant sphere, transforming a concept that seemed fictional into a complete tourist complex.
Four years after the first proposal, which never materialized, the responsible team returns with an even more ambitious plan. Instead of a simple “themed setting,” the Moon has gained the scale of a global mega-investment, with competition among countries like Australia, Brazil, China, Egypt, India, Poland, Spain, Thailand, the United States, and the United Arab Emirates to host the construction. Despite much anticipation, the project is still in the conceptual phase and lacks a defined location.
How the Largest Spherical Building in the World Will Look
At the center of the project is the sphere that would be the largest spherical building in the world, described as the largest and tallest truly spherical building ever constructed.

Hydroelectric project of US$ 170 billion initiated in Tibet with five cascading plants and a potential of 300 billion kWh per year, three times the generation of Three Gorges.

Chinese engineers begin filling a 217-meter dam at an altitude of 3,000 meters and prepare a 2,240 MW hydroelectric power plant to integrate hydropower, solar, and wind energy in the upper Jinsha.

São Paulo surprises the world and aims to become a reference in public transportation: the plan includes 200 km of new tracks, up to 14 lines, and simultaneous operation of 8 tunnel boring machines in mega projects by 2040 in the metropolitan area.

Fernando de Noronha will receive affordable houses made with lightweight concrete technology that facilitates transportation to the island; the investment is R$ 12.9 million and families must have an income of up to R$ 2,850.
The structure would have 271 meters in diameter and 312 meters in height, comfortably surpassing the Sphere in Las Vegas, which is currently one of the references in spherical architecture but is much smaller in size.
The proposal is for this “artificial moon” to be more than an architectural landmark. The idea is for visitors to feel as though they are entering another world as soon as they cross the threshold, with lighting, proportions, and ambiance designed to enhance the sensation of being in the presence of a celestial body on an urban scale.
A Complete Resort Inside an Artificial Moon
Inside, the largest spherical building in the world would house a large resort, with a hotel as its centerpiece featuring 4,000 rooms.
On the ground level, plans include a convention center, event spaces, restaurants, wellness areas, and even a smaller boutique hotel aimed at those seeking a more exclusive experience.
Atop this structure comes the most daring element of the Moon: a simulated lunar surface considered “authentic” by the developers, where visitors could walk as if they were on the Moon.
The project speaks of providing an immersive experience, but it has yet to detail how the sensation of walking in low gravity will be reproduced or what technological resources will be used for that.
Towers, Neighboring Spheres, and a Panoramic Ring Around the Moon
The main sphere of the largest spherical building in the world would not stand alone. The plan includes 20 towers around the artificial moon, connected by an elevated panoramic walkway that encircles the entire structure.
Conceptual images indicate that the top of this walkway will feature solar panels, suggesting that part of the complex’s energy demand could be met locally.
Additionally, the master plan calls for 16 smaller buildings in spherical shape in the vicinity, reinforcing the spatial theme and creating a skyline entirely based on rounded geometries.
Surrounding areas will also include extensive green spaces, parking structures, a transportation hub, heliport and vertiport operations, as well as luxury residences with renowned brands integrated into the complex.
Timelines, Uncertainties, and What May Change by 2032
Moon World Resorts speaks of inaugurating the largest spherical building in the world starting in 2032, if everything goes as planned.
The timeline, however, depends on factors such as the choice of host country, urban planning permits, financing, political acceptance, and the genuine interest of investors in backing such an uncommon-scale project.
Today, the Moon is still presented as a very conceptual undertaking. There is no guarantee that all parts of the plan will be executed exactly as they appear in the renders, and both the final design of the sphere and the set of towers, neighboring spheres, and attached areas may be adjusted throughout the negotiations with the chosen country.
What seems clear is that the project is born to be a symbol: a blend of tourism, entertainment, extreme architecture, and national branding for whoever manages to bring this “moon” to their territory.
Would you consider staying inside this giant “moon” if the largest spherical building in the world were built in Brazil, or would you prefer to visit it in another country?
