The first female pharaoh of ancient Egypt known for building monumental structures was Hatshepsut. Reigning from around 1479 to 1458 BCE, she oversaw an era of peace and prosperity. Hatshepsut is renowned for her ambitious building projects, including her mortuary temple at Deir el-Bahari, which showcased her architectural vision and the grandeur of her reign. Contrary to traditional gender roles, she often depicted herself in male attire and took on pharaonic titles, asserting her legitimacy in a male-dominated society. Hatshepsut's reign remains a significant chapter in Egyptian history.
