In 1984 we started our search for a pyramid city. How do you find a lost city?
Use the arrows to navigate through an introduction to our work.

We looked to the landscape and started the Giza Plateau Mapping Project. From 1984-1987 we mapped the geology and terrain, and studied the clues left by “human disturbance on a geological scale.”

We used this knowledge to build a model of how the pyramid builders organized the Giza Plateau for their building projects. We predicted their city must lie south of the Sphinx, near a large stone wall called the Heit el-Ghurab (or “Wall of the Crow”).

In 1988 we began to excavate this site and found a massive urban settlement containing barracks, bakeries, a livestock corral, officials’ houses, and a large royal administrative buildingall parts of a palace city and port that sprawled across the Giza Plateau.

As we dig, we save every scrap of material that the pyramid builders left behind – pottery, flint flakes from sharpening their tools, animal bones, and even plant remains from their diet.

We make some of our most important discoveries in the lab, through magnifying glasses and microscopes.

We use all of this information to help rebuild the everyday lives of the pyramid builders as in this 3D reconstruction. The gallery buildings shown here had unusually thick walls, which may have supported arched roofs and a second story. 

These gallery buildings are early examples of institutional buildings. Were they barracks where the pyramid workers were housed? Each was large enough to house 40 people.

Each gallery may have housed a “za” of 40 men as they served their term of compulsory labor for the crown. If so, we are finding the architectural footprint of early labor organization.

In 2012 we heard word of a discovery on the Red Sea coasta port of Khufu! At this site Pierre Tallet had discovered the Red Sea scrolls, the world’s oldest papyri. These papyri included the diary of a man named Merer.

Merer described working with his “za” to bring materials to Giza to build Khufu’s pyramid. They must have arrived by boat to deliver their materials to the building site.

We used evidence from the Red Sea Scrolls, along with findings from drill cores and excavations, to reconstruct a model of the ancient waterways needed to transport materials to Giza.

We are now excavating the possible location of the harbor at the Lost City of the Pyramids. Become an AERA member to follow our work and see what we find!

Who Built the Pyramids?

Who built the pyramids and how did the Pyramids help to build Egypt? These questions have driven our research at Giza for over 30 years.

We know the names of the kings who had the Giza Pyramids built: Khufu, Khafre, and Menkaure. Their monuments convey their power and the technical sophistication of their artisans, but tell us very little about the masses of people who did the actual work of building the pyramids 4,600 years ago.

Estimates for the number of people required to build the pyramids range into the tens of thousandsequal to the populations of the earliest cities. But who were these pyramid workers? Where did they live? What was their life like? In order to answer these questions, we realized we needed to find the pyramid builders’ city.

How do you find a lost city? We looked to the landscape. After three years of mapping and model building, everything we found  pointed to a site south of the Sphinx, near a large stone wall called the Heit el-Ghurab (or “Wall of the Crow” in English). So we started to dig and in 1988 we discovered the Lost City of the Pyramids, a massive urban settlement where people lived and worked while constructing the Giza pyramids.

Today we continue to work at the Lost City of the Pyramids, as well as the Great Pyramid, Sphinx, and the priests’ towns associated with the tombs of Pharaoh Menkaure and Queen Khentkawes.

Field School: Learning Bone

We believe the best way to train students is through a hands-on approach, embedding them in our current research projects. Here two of our archaeozoology students share their first-hand experiences studying ancient animal bones in our lab on the Giza plateau.

Pyramids of Giza

Who Built the Sphinx?

Our study of the Sphinx and the Sphinx Temple lead us to believe that Khafre created most of the Sphinx.

However, Khufu might have started it.


How Old Are the Pyramids?

Find out how we use modern scientific methods to test the accepted historical dates of several Old Kingdom monuments, including the pyramids at Giza.

AERA Object Typology

This richly illustrated book is intended to be used as a reference work for archaeologists working on other Egyptian (Old Kingdom) settlement sites.

This representative sample of everyday tools was selected from our massive collection and is the result of work on the material culture at Giza by a large team of specialists over more than 30 years.

The Red Sea Scrolls book

The Red Sea Scrolls: How Ancient Papyri Reveal the Secrets of the Pyramids

Pierre Tallet’s discovery of the Red Sea Scrolls—the world’s oldest surviving written documents—was one of the most remarkable moments in the history of Egyptology.

These papyri, written some 4,600 years ago, and combined with Mark Lehner’s research, changed what we thought we knew about the building of the Great Pyramid at Giza.

Giza and the Pyramids: The Definitive History

In this definitive book, Mark Lehner and Zahi Hawass provide insights into the history of the Giza plateau based on over 40 years of excavation and study.

The monuments are brought to life through hundreds of illustrations, including photographs of the monuments, excavations, and objects, as well as plans, reconstructions, and images from remote-controlled cameras and laser scans.
