Oxagon: Saudi Arabia’s Octagonal Floating City and the World’s Biggest Floating Port

Floating Port Oxagon: An Octagonal City on Water to Be Built in Saudi Arabia

The Saudi government has unveiled plans to build Oxagon, an octagonal port city in the country’s northeast. Developers say the city will be completed by 2030, house about 90,000 residents, and create roughly 70,000 jobs.

It will be the largest floating structure in the world and is part of the ambitious Neom project, which also includes a mirrored vertical city called The Line and the Trojena resort. All Neom developments are planned to run on renewable energy. The initiative is part of Saudi Arabia’s Vision 2030 plan to diversify the economy and reduce dependence on oil.

Oxagon — A City in Harmony with Nature

The octagonal Oxagon port will rise on the Red Sea near the Suez Canal and will serve as both a port and a logistics hub for Neom, according to Dezeen.

Most of the city will sit on water. The port—the planned largest floating structure in the world—will contain interconnected plazas, an oceanographic research center, a cruise terminal, and other infrastructure. The city’s main area will cover 48 square kilometers.

Project materials say it will be a place where “people, industry, and technology will exist in harmony with nature.”

Crown Prince Mohammed bin Salman said Oxagon will act as a catalyst for economic growth and diversification across Neom and the kingdom. He said the port will help rethink industrial development, environmental protection, job creation, and regional trade in Saudi Arabia.

The Giant Neom Project

Alongside Oxagon, Neom will include the long vertical city The Line and the Trojena resort, which will offer diverse landscapes and attractions.

Each element of the project stands out. The Line, with an estimated cost of $1 trillion, will stretch 170 kilometers and consist of two mirrored skyscrapers, each 500 meters tall. The city is expected to house 9 million residents and was designed by the American architecture firm Morphosis.

The Trojena resort, covering about 60 square kilometers in northwest Saudi Arabia, will feature a mix of natural and man-made attractions. Visitors will explore a nature reserve, stroll through meadows, and walk along a mountain lake. Plans include an observatory and ski slopes, with the ski area designed by the British firm Zaha Hadid Architects. Guests will stay in luxury apartments, and Trojena is expected to welcome its first visitors as early as 2026.
