text:  Temple 33 was a funerary pyramid erected over the tomb of Siyaj Chan K 'awiil I ( known as Burial 48 ) in the North Acropolis . It started life in the Early Classic as a wide basal platform decorated with large stucco masks that flanked the stairway . Later in the Early Classic a new superstructure was added , with its own masks and decorated panels . During the Hiatus a third stage was built over the earlier constructions , the stairway was demolished and another royal burial , of an unidentified ruler , was set into the structure ( Burial 23 ) . While the new pyramid was being built another high ranking tomb ( Burial 24 ) was inserted into the rubble core of the building . The pyramid was then completed , standing 33 metres ( 108 ft ) tall . The final version of Temple 33 was completely dismantled by archaeologists in 1965 in order to arrive at the earlier stages of construction .
