The female pharaoh who ruled Egypt during the 15th century BC and is known for her extensive building projects was Hatshepsut. As one of the few female pharaohs, she reigned around 1479-1458 BC and is celebrated for her ambitious construction initiatives, including her mortuary temple at Deir el-Bahari. Hatshepsut effectively portrayed herself as a male king, adopting traditional male regalia and titles to gain acceptance in a patriarchal society. Her reign is often regarded as a period of peace and prosperity, evidenced by trade expeditions and monumental architecture that showcased the power and richness of ancient Egypt.
