To the right of the Ball Court is the Temple of the Cosmic War. It is pretty much just a mound with 5 altars in front of it. I did not feel anything from this temple.
According to MAYAS and ZOCQUES Southeastern Mexico: Chiapas, ISBN 798-970-678-031-7, Page 45, (Laura Pescador Canton author), the Mayans enlarged this temple around 692 A.D., adding a rock temple to the upper part. They also placed 5 square altars in front of the temple’s northern face [the side facing the Temple Complex], with reference disks placed before each altar.
