Abstract

La Blanca (Petén, Guatemala) is an ancient Maya city located in the Mopan River lower basin that reached its highest peak during the Late Classic period. Its most important architectural complex is the Acropolis, a large pa-latial quadrangle rising about 8 m over the environment. It has 23 rooms much larger than other similar sets in the Peten area. Most of them preserve remains of its corbelled vaults, so it has been possible to study their geometric and structural features.One of the best preserved vaults is in the 5th room of the 6J2 Structure. After its excavation in 2007, it was documented by direct surveying tools, but today digital documentation techniques have allowed us to study in depth the construction technology of its vault, which keeps complete three sides and part of the exterior one, collapsed due to the disappearance of the original wooden lintels.Combining the information obtained from laser scan-ner and photogrammetric surveys, we have obtained a very useful model with geometric precision and photographic texture, which allow us to study the constructive details and the deterioration processes of the vault.
