measures and stands approximately tall. In October 2004 the south side of the pyramid collapsed; this is believed to have been caused by a combination of damage caused by the roots of nearby trees and water damage. The restoration of the pyramid with cement in the 1950s had converted the structure into a water trap, while cedar roots had penetrated the building to a height of causing significant cracking. Structure B1-2 underwent four phases of construction. The earliest phase had a total height of ; the lowest level measured high while the middle and upper levels both measured high. This first phase was completely covered by the second phase of construction, executed in three sub-phases (labelled 2A, 2B and 2C). This was built in a style very similar to that of the first phase, first with the extension of the lower two levels while still using the earlier top level; a new third level was added later, completely covering the previous version. The lower two levels were first raised to high; the middle level was then raised an additional and the upper level was increased to high. Finally, a fourth level was added to the pyramid, bringing its total height to . During the third phase of construction, the structure was increased from four to five levels. The levels varied in height between them, measuring , , , and respectively. The fourth and final construction phase was badly damaged by the collapse of the structure in 2004. Other structures Structure B1-3 and Structure B1-4 are the two structures that comprise the ballcourt. Test pits excavated during the first decade of the 21st century found the mortar floor of an I-shaped ballcourt. Structure B1-8 is a circular platform dating to the Late Classic period. Sculpture Sculpture at the site dates as far back as the Preclassic period. Two Terminal Classic to Early Postclassic chacmool sculptures were recovered from Tazumal, as well as a jaguar effigy sculpture and an anthropomorphic sculpture depicting the central Mexican deity Xipe Totec. These artefacts are stylistically similar to artefacts from central Mexico and the northern Yucatán Peninsula. One of the crude chacmool sculptures is housed in the Museo Nacional de Antropología in San Salvador; the other is in private ownership. Metal artifacts Three gold ornaments have been excavated from Tazumal. They were created using the lost wax method and have been tentatively dated to the 8th
