What is "wajxaklajun"

Wajxaklajun (pronounced ) (also known as Yolk'u, El Calvario, Carvao, and Curvao) is a ruin of the ancient Maya civilization situated adjacent to the modern town of San Mateo Ixtatán, in the Huehuetenango Department of Guatemala. Wajxaklajun is considered to be the most important archaeological site in the San Mateo Ixtatán area. The site has been dated to the Classic period (c. 250–900 AD). The Chuj Maya consider the city to have been built by their ancestors. The site has similarities with other nearby highland Maya ruins; it is unusual for the presence of a number of stelae, a feature more associated with lowland sites during the Classic period, probably indicating some level of exchange with lowland cites.
