Luxor's pyramid atrium (claimed largest atrium)

The Luxor Hotel's pyramid contains an enormous open interior space often cited as one of the world's largest hotel atria; some sources describe it as the world's largest atrium, though such rankings depend on measurement criteria and are sometimes debated. The atrium's dramatic, sloping interior and high vertical clearance are defining architectural features of the Luxor's pyramid design. The atrium houses guest rooms lining the interior and contributes to the resort's distinctive interior environment.
