Equally new amid the museum scrum is Natural History Museum Abu Dhabi, which rises above the Arabian Gulf as a succession of giant sugar cubes and is inspired by the region's geology. And then there's the much-talked-about, much-delayed, largest-ever Guggenheim Abu Dhabi. Expect the cavernous modern art gallery in late 2026 or even beyond that. (Just don't mention the projected US$1bn/£751m cost.)
