Ocosingo

Ocosingo, a town in the Mexican state of Chiapas, 65 m. S. E. of Ciudad Real; pop. about 4,000. It derives its principal interest from a series of extraordinary aboriginal monuments in its vicinity, which closely resemble those of Palenque. They have been in part described by Mr. Stephens in his " Incidents of Travel in Central America," and by Capt. Dupaix in his report to the Spanish crown on the antiquities of Mexico.
