The Maya lived in what is now Mesoamerica from about 2000 BCE until 1697 CE, from southeastern Mexico, through Guatemala and Belize into western Honduras and El Salvador. They developed settled agriculture focused on maize, beans, chili peppers, and squash and early villages that became a complex society with the first cities developing around 750 BCE and monumental architecture around 500 BCE and hieroglyphic writing around 300 BCE. The last city of the Maya, Nojpetén, fell to the Spaniard colonizers in 1697, though many villages remained, too remote for the Spanish authorities, that maintained the Maya way of life while incorporating steel tools to improve agriculture while practicing their traditional crafts and maintaining their traditional language and beliefs despite the efforts of Catholic missionaries, with millions remaining today.

Uaxactún was a sacred site located in the Petén Basin in Guatemala was known as Siaan K'aan, or 'Born in Heaven', to the Maya, with the modern name given when it was rediscovered in 1916 and it's Maya name not known until the 1990s. The modern name is from the Maya words meaning 'Eight Stones', which comes from an inscription with the date 8th Baktún, making it at the time the oldest known Maya date, as well as sounding like 'Washington', home of the Carnegie Institute, which funded the explorations of the area. It is 19 km north of Tikal, one of the largest sites and urban centers that was likely known as Yax Mutal to the Maya.

Los Abuelos is approximately 21 km from Uaxactún and dates back about 3000 years. It covers about 15.5 sq km and has pyramids and stone figures of a man and woman who are 'thought to be symbolic of an ancestral couple', giving the site 'cultural and symbolic meaning' and leading to the name Los Abuelos, which means 'The Grandparents'. One of the pyramids, which is about 33m tall, has two chambers that have been well preserved and are decorated with red, white, and black murals. There is also a nearby astronomical observation arrangement of structures that are likely older than similar structures in the area, giving researchers further information on the development of the Maya calendar and ritual practices. It is thought that the purpose of the site was ceremonial rather than political.
Research in the area is part of the Uaxactún Regional Archaeological Project (PARU), a joint project between Guatemalan and Slovak archaeologists, which has been ongoing since 2009 and has thus far studied 1,200 sq km and has found 176 sites, excavated 20, and determined three of those to be major centers.
