 Taharqa is the only king that made additions to the complex, building the Edifice of Tarhaqa to the forecourt between the First and Second Pylons.This meant that the avenue of sphinxes were moved to the sides of the court, where they are still located.He also added a colonnade to the Precinct of Montu

The last major change to the temple's layout was the addition of the first pylon and the massive enclosure walls that surround the whole Karnak complex, both constructed by Nectanebo I, completing the layout started by the kings of the 22nd Dynasty.
