triadic architectural complex. Two plain stelae were found in Group C. The East Structure of Plaza C had 2 plain circular altars that were found during excavations of its facade. These altars may have been moved there from elsewhere in the city. The structure had several levels and in the Terminal Classic a cist was inserted into the upper level and closed with limestone slabs. A dedicatory offering was placed on top of it, consisting of an obsidian blade and eleven ceramic vessels. Within the cist were enclosed the remains of an adolescent together with a rich funerary offering that included 2 ceramic vessels, an alabaster vase, and a variety of ornaments, rings and beads crafted from snail shells, mother-of-pearl, greenstone and pyrite. Group B Group B (also known as the East Group) occupies the upper terrace. It was accessed from Group A via a long causeway that measured wide and was bordered by parapets. Group B consists of 9 structures built upon a single basal platform and arranged around 2 plazas, D and E. Plaza D consists of a large traditional E-Group astronomical complex that may have been more important ritually than a similar complex in Group A. The plaza covers an area of . The E-Group west pyramid measures high The east platform is lower, as is normal in such complexes in the wider Maya region, although it is considered unusual for the southeastern Petén. It stands high. Plaza E (also known as the Northeast Plaza) has a north structure that is of a similar form to the east platforms of E-Group astronomical complexes, with a small temple mounted upon the central portion of a longer platform. It is the only example of this form of architecture in the Dolores region that is not part of a formal astronomical complex. The North Structure of Plaza E contained a large cache of Terminal Classic ceramics, including hundreds of simple plates and a variety of incense burners. The plates were all bound with vine and were likely to have been placed in the structure by traders. Monuments The monuments found at Sacul include six sculpted monuments, five plain stelae and seven plain altars in the West Group. Two rows of stelae were erected in front of the East Platform of Plaza A, with five stelae in the rear row. As well as the numbered monuments listed here, various unnumbered pieces
