The reassembled Khufu ship is just located beside the Khufu Pyramid, and it can be dated back to 2500 B.C.  During the 1950s, archaeologists discovered that thousands of wooden pieces were pressed under huge limestones. Surprisingly, there was only one wooden oak that was broken after almost 4,500 years. Also, we have found related wall paintings in the tomb of Ty, a noble's tomb that can be dated back to 2500 B.C. The only difference is that Khufu ship is driven by manpower, while most of the wall paintings are about sailing boats, which are wind-driven.
