Attractions in San Jose, the capital of Costa Rica: National Theater, National Museum, Chinatown, San Jose street scene, etc. The last picture is the famous Costa Rican stone balls (in the 1930s, Americans discovered more than 200 stone balls that seemed to be artificially carved in the uninhabited delta tropical jungle of Costa Rica. The largest ones have a diameter of dozens of meters, and the smallest are only as big as marbles. The craftsmanship is exquisite and it is a unique one).
