On the road from Emiliano Zapata, about 30km west of Tenosique, the ruins of Pomoná are reached 4km down a signed track. Although the site, located in rolling countryside with views of forested hills to the south, makes a pleasant diversion, a visit is really only for the dedicated. The restored structures date from the Late Classic period; the site’s largest building is a stepped pyramid with six levels. Pomoná was a subject of the much larger city of Piedras Negras in Guatemala, further up the valley of the Usumacinta. The small museum (daily 10am–4pm) houses some interesting carved panels and stelae.
The archaeological site takes its name from Pomona, tributary of the lower Usumacinta river. Cultural significance: Pomoná or Pakbul, as the hieroglyphic name is read, it was an important prehistoric settlement during the Late Classic period between 600 and 800 AD, a period in which formed an independent political entity. Its geographical position allowed him to play a major role in the cultural exchange between the contemporary sites of Upper and Lower Usumacinta policy consolidation brought its territory dependence on sites like Panjale located to the south, in Boca del Cerro and a little Chinikiha to the south and also held war for territorial control relationships with the manors of Palenque, Piedras Negras and La Mar.
