Thutmose I
Thutmose I organized great building projects during his reign, including many temples and tombs. His greatest projects were at the Temple of Karnak under the supervision of the architect Ineni. Before this, Karnak probably consisted only of a long road to a central platform, with a number of shrines for the solar boats along the side of the road. Thutmose had the temple made much bigger. He had a fifth pylon built along the temple's main road. He built a wall around the inner temple and two flagpoles on either side of the gateway. Outside of this, he built a fourth pylon and another enclosing wall. He built a hypostyle hall between pylons four and five. This was made with columns of cedar wood. This was common in ancient Egyptian temples, and supposedly represents a papyrus marsh, an Egyptian symbol of creation. Along the edge of this room he built very large statues, each one alternating wearing the crown of Upper Egypt and the crown of Lower Egypt. Finally, outside of the fourth pylon, he built four more flagpoles and two obelisks. One of them, which now has fallen, was not inscribed until Thutmose III about 50 years later. The cedar columns in Thutmose I's hypostyle hall were replaced with stone columns by Thutmose III, however at least the northernmost two were replaced by Thutmose I himself. Hatshepsut also erected two of her own obelisks inside of Thutmose I's hypostyle hall.
