Xanadu would have been another resort that would have completely revolutionised Las Vegas and brought a number of features to the Strip much earlier than they would have. Proposed in the 1970s on the land where the Excalibur now stands, it would have been a pyramid-like building that would have been among the biggest on the Strip at the time. It was set to have a huge central atrium, similar to the Luxor today, as well as a convention centre, casino, showroom and more.

Priced at $150million, plans eventually fell through because at the time the city’s sewer lines simply wouldn’t have been able to manage with the 1,700 hotel rooms, as well as other amenities, proposed for the site.
