Pilasters are composed by panels with vegetal decoration, whose measures rang in width between 27 and 30 cm and in height between 30 and 60 cm.
No such item was found in situ, but the elevated number of finds along the central courtyard perimeter attest to their important role in the architectural decoration of the antechambers. Current hypotheses also relocate them on the back wall of the throne hall, possibly flanking the throne itself. Pilasters show a carved, modular decoration. Four patterns have been reconstructed so far; others are still unidentified. Type 1 counts the majority of finds and it is attested by stucco finds as well (see Stucco/Pilasters).
