Yaxchilan: One of the structures at Yaxchilan

Most of the known buildings and monuments have been dated to the Late Classic period (ca. 600\u2013900). The Late Classic architecture at Yaxchil\u00E1n, as in Structures 6, 19, 20, 25, 30, 33, 39 and 40, features doorways with sculptured stone lintels, heavily decorated upper fa\u00E7ades filled with stone and stucco sculptures, and high roof-combs (ornamented stone extensions above the temple roofs) pierced by holes and covered with sculptures. These features can be seen best in Structure 33 , which typifies the monumental architecture at Yaxchil\u00E1n. This building is set on a hill that rises 50 m behind the Main Plaza and consists of a single row of vaulted stone rooms with three doorways, each with a carved stone lintel commemorating the accession of the Maya ruler Bird Jaguar IV. The heavily decorated fa\u00E7ade above the doorways includes the remnants of three seated figures, and the great double-walled roof-comb, which rises another 6 m above the roof, included a huge figure of a man, assumed to be Bird Jaguar, seated on a throne.
