Mega-cities designed for tourism and sustainable living are emerging around the world, promising to redefine the travel experience. Inspired by Saudi Arabia's NEOM, these ambitious projects blend cutting-edge technology, eco-friendly infrastructure, and luxury accommodations to attract global visitors. From Bhutan's Gelephu Mindfulness City to Greece's Ellinikon and Egypt's New El-Alamein, each development aims to offer a unique blend of innovation, culture, and natural beauty.

While some projects have faced financial hurdles and delays, their scale and vision continue to inspire similar initiatives in countries such as Montenegro, Uzbekistan, and Mexico. These new urban hubs feature everything from autonomous governance and renewable energy to luxury resorts and cultural landmarks. Despite debates about their authenticity and appeal, these mega-cities represent a bold step towards the future of tourism, combining sustainability, technology, and architectural marvels.
