The Playa Arena is located in the center of the historic city of Pla in Croatia. It was built in 27 B.C. and 68 A.D. It is the only stadium in the world that preserves complete Roman architecture. The whole oval shape is not destroyed. The auditorium has three floors. It can accommodate 23,000 spectators. It is unexpected that there is such a miraculous ancient building as the Colosseum in Croatia, which is comparable to the Colosseum in Rome. Many local cultural activities such as concerts, operas, ballet performances are also held here.
