Qasr Al Watan
The working presidential palace at the heart of Abu Dhabi, opened to the public in 2019. The Great Hall sits under a 37-metre dome, and the House of Knowledge holds manuscripts tracing Arab contributions to science and astronomy. Allow two hours; an evening light-and-sound show is projected onto the facade.
Louvre Abu Dhabi
Jean Nouvel's museum on Saadiyat Island, where a 180-metre latticed dome filters sunlight into what the architect called a rain of light. The galleries are arranged by era rather than by nation, placing works from different civilisations side by side, and include loans from the Louvre in Paris. Allow two to three hours.
