Cirque du Soleil's 'O' water show at the Bellagio

'O' is a long-running, water-themed Cirque du Soleil production staged in a custom aquatic theater at the Bellagio that debuted in 1998. The show is notable for its integration of synchronized swimming, diving, and acrobatics in and above a pool and is a documented permanent entertainment offering at the resort. Locals and reviewers sometimes make lighthearted jokes about the show's elaborate staging and the idea of a "water park" style production in the middle of the Strip.
