King Abdul Aziz International Conference Center

When the King Abdulaziz International Conference Center in Riyadh, Saudi Arabia opened in 2017 (Arabic for "Ithra"), it instantly became an icon; not just because of its jaw-dropping design, which represents a pile of oil-bearing rocks flattened by desert winds, all wrapped in 350 kilometers of steel pipe. But also because of its ambitious vision as Saudi Arabia's first fully cultural destination. Simply put, it is a structure that must be seen to be believed.

Inside, you'll find an astonishing 85,000 square meters of space housing a museum, theaters, libraries, cinemas, exhibition halls, creative labs, and knowledge towers. Its grand hall and impressive architectural scale are so vast that you might need an entire day to appreciate the wonders of Ithra.
