The investment, near the theme park of Port Aventura in Tarragona, comes at a time when the country's real estate market continues to slide after a property bubble burst in 2008.
No financing details were immediately available. The investment comes just a week after Catalonia's regional government applied for just over 5 billion euros from a state credit line aimed at helping its liquidity position.
Catalonia is expected to fail in its bid to attract a separate planned gambling complex to be built by Las Vegas Sands. Spain's 17 autonomous regions remain firmly shut out of capital markets.
