Edifice XXXIX (Roman numeral “39”) is the 2nd best preserved temple on the hilltop (Edifice XL [“40”] is the best preserved).

According to YAXCHILAN: The Design Of A Ceremonial City by Carolyn E. Tate, Copyright 1992, ISBN 0-292-77041-3, Page 230, Edifice XXXIX (“39”) has a strange orientation, facing far to the north of Edifices XL (“40”) and XLI (“41”).  The temple sits on a platform of 7 steps with a base forming an additional step.  Edifice XXXIX (“39”) has 3 doorways near the temple’s front center.  A curtain wall inside separates the chamber into 2 dark, narrow spaces on the east end.  Edifice XXXIX (“39”) included a stela (X [“10”]) in front with Altars V (in front of the stela), VI (in front of the central doorway), and IV (inside the central doorway).  Edifice XXXIX (“39”) probably dates from the early part of Bird Jaguar’s IV reign (circa 15 February 766).
