The third pylon (through the hypostyle hall) was the designed as the grand entranceof the temple, built by Amenophis III. He also used blocks from other demoloshed parts of the temple — much of the stone here has been removed by archeologists and reassempled in the Open Air Museum
Between the third and fourth pylon are the remaining obelisks in the temple. Originall there were four, only one of which still stands here. Through the fourth pylon stands the red granite obelisk of Hatshepsut.
THe fifth and sixth pylons begin to approach the original portions of the temple of Amun. Thutmosis I most likely built the fifth pylon of limestone and behind it lies the original couryard of the temlpe. Only a small portion of the sixth pylon remains, leadingot the sanctuary
