Hatshepsut was responsible for building the obelisks in the temples, a design that had never been used before. She also built a magnificent temple near the Valley of the Kings.
We do not know what happened to Hatshepsut after 1458 BC because she suddenly disappears from the records and Thutmose III takes over as pharaoh.
Thutmose III had as many of Hatshepsut's shrines, statues and reliefs hacked away as he could find and removed her name from the lists of pharaohs.
But the obelisks were sacred monuments and he could not have them defaced. So, instead, he had brick walls built around them.
