The Acropolis looks over the great plaza of Quirigua and is the only major excavated building. Although, the jungle still has much of the city in its grip. The site is small and unadorned.
The other unique item of Quirigua other than its Stelae are its Zoomorphs. Zoomorphs are carvings of mythical animals that often combine the characteristics of many animals into one. Frogs, Snakes and Turtles are re-occuring themes.
Quirigua is primarily famous for its well-preserved Mayan Stelae. Most have not been looted as was the case in many other Mayan sites.
Quirigua is located at one of the most important highways in Guatemala, the Carr. al Atlantico. All buses going from/to Guatemala-Flores or Chiquimula/Esquipulas-Puerto Barrios will drop you at the entrance of the village of Quirigua, the road to the ruins or in Los Amates (1,5km from the Quirigua village, where you will find an ATM and more "comedores" (restaurants).
You can pick you buses in the road as well, but I think it is easier to get to Los Amates (as I did). It is just a $1 ride (5min) with a tuk-tuk to get there
Quiriguá (pronounced Kiri-gua) is a relatively small site, almost directly across the border from Honduras' Copán. Strategically located on the Montagua River trade route, which was important for the transport of jade and obsidian, it was also originally a vassal of Copán. However, Quiriguá rebelled and defeated Copán, then allied itself with Calakmul, after which it erected elaborate stone monuments in a style similar to that of Copán. In fact, one of the monuments at Quiriguá, known as "Stele E," is the largest known quarried stone in the Maya world, standing 35 ft (10.6 m) tall and depicting a Mayan lord over three times life size. VirtualTourist members suggest crossing the border and also visiting Copán, since the two sites share so much history and Copán had such a large cultural influence in the Classic period. The must-see highlight at Copán is the Hieroglyphic Stairway, which contains more than 1,800 individual glyphs, making it the longest known Mayan hieroglyphic text.
