Hard Rock International has promised to invest one billion euros for an integrated casino resort (IRC) at the Hellenikon International Airport site near Piraeus if it wins the international tender for a gaming licence for the site that is considered the biggest property development in Europe.

According the naftemporiki.gr site, Jim Allen, the president of Florida-based Hard Rock and CEO of Seminole Gaming, presented the offer ahead of next month’s deadline for the submission of bids.

Mr Allen said roughly 250 billion euros were from Hard Rock International funds with the remainder from foreign and domestic lenders.

The IRC for the old airport site includes hotels, a conference centre, food-and beverage  areas aswell as  leisure and amusement areas.

On January 20, a rival casino group, the US-based Mohegan Gaming & Entertainment based in Connecticut were granted the initial rights to develop a casino resort on the site. They were awarded the lone licence by the Hellenic Gaming Commission. Mohegan had created a consortium with Greek construction firm GEK TERNA to bid for the licence for the site.

Hard Rock had ten days to appeal against that decision.
