Palenque’s site museum is worth a wander, displaying finds from the site and interpreting, in English and Spanish, Palenque’s history. Highlights include a blissfully air-conditioned room displaying a copy of the lid of Pakal’s sarcophagus (depicting his rebirth as the maize god, encircled by serpents, mythical monsters and glyphs recounting his reign) and finds from Templo XXI. Entry to the sarcophagus room permitted every half hour.
