As you walk up into the Grand Plaza, the Ball Court is on your immediate left. Just another standard generic Ball Court; nothing to get excited about. I did not feel anything from this Ball Court.
According to the LONELY PLANET: Guide to Mexico, 9th Edition, (2004), ISBN 1-74059-686-2, page 811, the Mayans inaugurated this Ball Court around 780 A.D., under the female ruler Smoking Mirror.
According to MAYAS and ZOCQUES Southeastern Mexico: Chiapas, ISBN 798-970-678-031-7, Page 45, (Laura Pescador Canton author), the Mayans renovated this Ball Court in 692 A.D. They placed a large stone commemorating the event, which states that the Mayans renamed it the “Ball Court of the 3 Conquests”.
