The megacity you haven’t heard of is in China and aspires to be the largest in the world

In the world there are big, huge, huge cities and then others that are almost a country in themselves, like Jing-Jin-Jithe huge conurbation that has been taking shape in northern China for years. And “country” can be taken in its most expansive sense. If they are fulfilled the forecasts launched by its promoters more than a decade ago, the megalopolis will host between 110 and 130 million of inhabitants, in addition to a robust business muscle. Its size will also take away the hiccups: is spoken of more than 200,000 km2double that of all of Portugal. It may sound like science fiction, but there is a very simple explanation: Jing-Jin-Ji is not a city founded from scratch, but a new way of understanding and organizing Beijing, Tianjin and the province of Hebei to shape an urban titan. Rethinking Beijing. Although it does not reach the levels From Tokyo, Delhi or even Shanghai, Beijing is one of the most populous cities on the planet. Its stable population easily exceeds 20 million of people, more than all Romania or Netherlands. That huge number of people move every day to go to school, the doctor and of course to companies that may be close by. several hours of their houses. If we add to that the role of Beijing as the capital of one of the greatest potentials in the world, the result is an (almost) impractical megalopolis, polluted and in which complications the services. To face such a challenge and prevent the exodus from the countryside from ending up collapsing the city, in recent years the Government has resorted to several solutions. One has been limit the population. Another is to rethink Beijing itself so that it is no longer just the capital of China or a mere metropolis, but part of a much larger conurbation. The objective is twofold: to relieve pressure on the capital and to promote a new industrial hub, one capable of replicating the success achieved in the Yangtze River Delta or Guangzhou and Shenzhen area. A new giant: “Jing-Jin-Ji”. With this premise, a decade ago the Chinese authorities decided to go for what is probably one of their most ambitious projects: Jing-Jin-jia word that hides a nod to the cities of Beijing, Tianjin and Ji, which is how the province of Hebei is traditionally known. That business card speaks for itself idea. The idea is strengthen the bond between those three territories in northern China, distributing part of the crushing burden that now falls on the capital, improving communications and betting on a distribution of specialized roles. The story of Jing-Jin-Ji can soar at least to the National New Urbanization Plan presented by the Government for the period 2014-2020. In it, China, a nation already accustomed to megacities, advocated the promotion of a dozen “urban clusters.” The greatest of all would be Jing-Jin-Ji, in which Beijing would embrace (in an almost literal sense) with Tianjin, which is another of the biggest cities of the country and nearby cities in Hebei province. More than theory (and politics). The project received Xi JinPing’s blessing just 12 years ago, in April 2014and was sold with a display of astonishing data. Its objective was neither more nor less than to bring together a region of more than 215,000 km2 in which some 130 million people would live in 2050, generating a powerful industrial and commercial hub. It could have remained just that, an ambitious idea, but a quick review of the newspaper library confirms the extent to which China was determined to push it forward. The following year, in 2015, The New York Times confirmed that Jing-Jin-Ji was beginning to become a reality. Shortly after Guardian informed of the plans to create Xiongan, a large city located just under 100 km from Beijing that would allow the urban framework of Jing-Jin-Ji to be articulated. It was just one of the measures to consolidate the new megalopolis. The most effective of all was the reinforcement of rail and road communications. In 2016, China actually approved an ambitious investment plan to build kilometers and kilometers of roads and reach the middle of the century with about twenty of railway lines. Is it just infrastructure? No. Improving communications is a fundamental part of Jing-Jin-Ji, but not the only one. Another, equally important, is the distribution of roles between the regions. He starting point It was simple: Beijing would consolidate itself as a political, cultural and technological center while Tianjin would establish itself as an export port and manufacturing hub. As for Hebei, there was a commitment to also orient it towards industry and wholesale trade. In the background, slide China Briefingthere was the desire to bet on industrial clusters focused on emerging sectors, such as electric vehicles, the biopharmaceutical industry or robotics. To achieve this distribution, of course, it was not enough to set guidelines on paper. In 2015, the Beijing authorities announced his plans to refocus the capital, moving certain services, such as wholesale markets and administrative offices, out of the urban center and moving some services to suburban areas or even to Hebei province. The importance of gestures. Perhaps the best proof of the extent to which the Government wants to keep the project alive is that, from time to time, the Chinese press publishes articles reviewing the progress in the creation of Jing-Jin-Ji. It happened in April 2024coinciding with the tenth anniversary of the presentation of the plan, and it happened again in 2025, when CGTN He published an article to make it clear that Beijing’s suburban dream is advancing little by little. His chronicle highlights the increase in economic production in the region, the opening of new stretches of road that allow travel times to be cut, the reinforcement of public transport or collaboration at an economic level and when providing services. The local press also highlights that the region “has become an innovation center” capable of attracting companies. Of course, there are also important challengeshow to achieve greater … Read more

Years ago someone dreamed of a floating megacity. The result is a 550-meter “terayate” for 60,000 people

The ocean is full of infrastructures that once sounded crazy. With his almost 400 meters in length the ship Ever Given would surely sound like science fiction to any 19th century engineer, as would the ability of the Blue Marlin to transport infrastructure the size of an aircraft carrier or the gigantic dimensions of the ship’s engine Emma Maerskwhich at 13.5 meters high and 27 meters long looks more like a mansion than a machine. In naval engineering the limit is your imagination. Or, if the technique still does not allow you to translate the idea into reality, wait long enough. The Italian designer must have thought something similar Pierpaolo Lazzarinifrom the Lazzarini studio, who in 2009 began to think about a crazy idea: building a floating megacitya gigantic structure capable of hosting tens of thousands of people, hotels, commercial spaces, parks and even facilities for aircraft and other smaller vessels in the middle of the ocean. Breaking the mold Not only that. Already starting to dream – Lazzarini must have thought – why not give it the appearance of a terayate, a boat format so large that it surpasses the super, mega or even “gigayacht” categories. And curling the curl a little more: Why not design that mass to look like a sea turtle? It seems crazy, but that’s what came out of the workbench of Lazzarini, a studio that has already made headlines for its designs. dream vehicles, luxury boats, flying devices either architectural proposals floating. Of course, without the caliber of his latest idea. His proposal is called Pangeos and was presented as nothing more nor less than an immense “itinerant floating city”a chelonian-shaped vessel of 550 meters in length and a beam of 610 m at its widest point, measurements that would make it a true titan of the seas, much larger than the Ever Giventhe transatlantic Wonder of the Seas or even the Seawise Giant. “At the moment it’s just a concept, but it’s starting to become more than just computer animation,” Lazzarini recognizedwhich launched an online dossier with images and videos. In an attempt to go further, in 2023 its promoters promoted an NFT crowdfunding to sell “virtual spaces”. All in all, it does not seem that Pangeos will become a reality in the short term. The studio estimates that shaping its project would cost around 8 billion dollars and the work that would last about eight years. Once finished it would become “the largest floating structure ever built”, with 60,000 accommodations. Its hull will be divided into 30,000 floating cells. Its wings are designed to get energy of the resistance and the waves that break against the hull and along its roof there would be solar panels that would supply it with energy. The vessel, with a draft of approximately 30 meters, would be capable of moving at a speed of five knots. Building a record structure requires record resources. Not only because of the enormous amount of funds and work that Pangeos would need. Giving it shape will require a huge shipyard—”tera shipyard,” he points out—in which they have also thought. The idea is to have a facility with a dock that can be flooded to allow it to float once the yacht is finished. The structure designed by the studio would 650 meters wide by 600 long and would have its own access to the sea. As for where, those responsible have opted for Saudi Arabia, a location located about two kilometers from the King Abdullah Harbor. Although Pangeos is fascinating and its structure seems straight out of a science fiction movie, it is not the first floating community project. Long before Lazzari, other studios embarked on the adventure of designing their own traveling cities. One of the most recent is the MV Narrativean exclusive residential ship of 229 meters in length and 547 “residences-cabins”. The crown of the projects, however, goes to another structure worthy of the most fertile imaginations: the enormous Freedom Shipa boat designed for 100,000 passengers. Norman Nixon launched the proposal in the 90s, but so far he has not managed to put his impressive infographics into practice. They all share the same basic ingredient: ambition and imagination.
