San Bartolo

San Bartolo is an archaeological Maya site in Guatemala’s Petén Department best known for its early painted murals. The murals are significant for their age and for providing rare painted narrative art from the Late Preclassic Maya period.

The principal highlight is the series of well-preserved wall paintings found inside a buried temple-pyramid, showing complex iconography and early glyphic elements. The painted scenes include mythological and ruler imagery rendered on plaster, and the mural complex is a primary reason researchers visit.

Excavations at San Bartolo began in the late 20th century and intensified in the early 2000s, revealing the painted rooms inside a constructed pyramid. The site dates to the Late Preclassic Maya era, and the murals have reshaped understanding of early Maya ritual and royal imagery.

San Bartolo lies in the Petén lowland forest of northern Guatemala, within the region where many Classic and Preclassic Maya sites are located. The site is set in tropical lowland terrain and is approached via forest tracks and archaeological access routes.

• Dating: Painted plaster murals have been dated to the Late Preclassic Maya period, around 100 BCE or slightly later, making them among the oldest known Maya murals.
• Access: Located within lowland rainforest and an archaeological reserve; on-site access is controlled and often requires a guide or permission from local authorities.

What to See#

• Las Pinturas: Mural-bearing complex first excavated in the late 20th and early 21st centuries; features painted plaster panels with figurative scenes and Maya iconography.
• Painted pyramid (Temple): A buried pyramid that contained the painted rooms, constructed during the Late Preclassic period and central to the site’s ceremonial architecture.

• San Bartolo (Peten) is best visited with a licensed local guide or tour operator based in Flores-many of the archaeological sites around Petén have restricted access and guided visits are the reliable way to get current access information.
• Check in advance whether the site or its murals are open to visitors and whether conservation work has closed areas; access can be limited to protect fragile painted surfaces, so don't assume the site will be fully open on arrival.
• Plan visits for the cooler morning hours to avoid the midday heat and to maximize time for photography and interpretation with your guide; bring insect repellent and be prepared for rural dirt‑road travel.
