Unfinished Obelisk is situated at north of Aswan, about 4 km from the train station. It was constructed by Queen Hatshepsut, who ruled Egypt during the 18th dynasty. She also constructed  the temple in Deir El Bahari on the west bank of Thebes. Name obelisk is Greek origin. It is piece of monolith, with four sides a small pyramid at the top called pyramidion. Its function seems to be firmly linked to the sun cult of Heliopolis.

Unfinished Obelisk is the biggest known obelisk in the Ancient Egypt. If it was completed it would be high about 42 meters and weigh almost 1,200 tons.

From there do not know anything more. In the study of these giant monuments we found two problems. The first is the stone work. It seems inexplicable how so hard granite stone obelisk was made with copper tools. On the other hand, we find perhaps the most intractable problem. How did the Egyptians move thousands of tons of stone without breaking the fragile structure of the obelisks? How did the Egyptians manually load what today we can not do with our best machines? There is a theory that it has been transfered dragging it to the river, where it was shipped on a big boat made of papyrus and wood.

The possible answer can be found in some of the reliefs of the temple of Queen Hatshepsut built on the cliff of Deir el-Bahari. Here we can see some reliefs showing ships moving obelisks on Nile river. But more than an answer to our question, the relief seems to offer a major surprise as the ship carries two obelisks at once.

What kind of boat could carry more than 2,000 tons on a river? If we add that the Nile is full of shoals, where often modern ships are caught, it seems inexplicable how the Egyptians could transport these large obelisks hundreds of kilometers downstream.

It is certain that the Egyptian obelisks offer a series of mysteries that experts have failed to resolve.
