The Sinaia Casino is located in "Dimitrie Ghica" park, Sinaia, Romania and was built at the initiative of King Carol I of Romania.
Construction began in 1912 and was finished a year later. The work was supervised by architect Petre Antonescu, who was also the author of the plans. The main shareholder in the casino was Baron of Marçay, a shareholder in the Monte Carlo Casino. The opening was celebrated with fireworks and a piano recital by George Enescu, and it became a major attraction between the wars.
After the communist takeover in the 1940s, gambling ceased and the casino is now an international conference center.
