Originally commissioned by King Carol I around 1900, the Casino first opened to the public in 1910.
Commanding a dramatic location right on the waterfront of the Black Sea overlooking the ancient port at Constanta, the Casino was a triumph of the Art Nouveau movement, and quickly became the symbol of the city. Worsening circumstances in Romania over the 20th century saw it gradually fall into disrepair, briefly used as a hospital during World War II and eventually repurposed by the communist regime as a restaurant. Maintaining the elaborate structure quickly became prohibitively expensive, and the building was closed in 1990.
Despite occasional efforts at restoration, it's remained abandoned ever since. While it's nominally owned by the municipality and technically closed to the public, Romanian authorities have never shown much interest in enforcing the closure.
