The 22-acre Dragon City Hotel and Resort casino site in Las Vegas, US, is to be put up for auction.

The property is being sold by Spring Mountain Wynn Investments, subject to the approval of the US Bankruptcy Court. The land is available to use for a hotel and casino complex, with all zoning permits and approvals currently in place for a 28-storey, 2,200-room hotel and 500,000sq.ft gaming space.

"The site could be the largest single asset ever sold at an open outcry real estate auction in the history of the world," said Michael E Berland, executive vice president and principal of Chartwell Group’s accelerated marketing division. "This is a highly strategic opportunity for buyers to acquire a fully entitled casino site in an unparalleled location."

The auction is to be held at the MGM Grand Hotel and Casino in Las Vegas on May 16.
