Unfinished Obelisk

A single granite obelisk lying in the quarry where it was cut, still joined to the bedrock along its underside. Had it been finished it would have stood about 42 metres and weighed in the region of 1,090 tonnes — larger than any obelisk ever raised, anywhere.

It never left. A crack opened across the shaft while it was being cut free, and the whole project was abandoned where it lay. That failure is the reason the site is so useful: nowhere else can you see every stage of the process frozen mid-work.

What to look at

• The trenches along both sides, just wide enough for a man to crouch in and swing at the rock
• The pounded surface — a shallow, dimpled texture left by hammering rather than cutting
• The crack itself, running diagonally across the shaft
• Test holes and abandoned starts elsewhere on the quarry floor

It is a small site and a short visit, usually paired with the High Dam and Philae. Go early — the granite radiates heat and there is no shade at all.

The obelisk is generally attributed to Hatshepsut, in the 15th century BCE, and may have been intended as a companion to the one she raised at Karnak, which still stands and is the tallest surviving ancient obelisk in Egypt.

How you cut a thousand tonnes of granite

Aswan granite is harder than the bronze tools of the period, so it could not simply be chiselled. Instead, workers used balls of dolerite — a stone harder still — held in the hand or bound to weighted handles, and pounded the granite into powder along the line of the cut. Trenches were sunk on each side until the shaft stood free, then undercut from below.

Experiments have shown the method works, but slowly: measured rates suggest years of continuous work by large teams for a single monument of this size.

Why it was left

The crack was fatal. There was no repairing a flaw of that scale in a monolith intended to stand for eternity, and the stone was not worth reclaiming for anything smaller. So the quarry recorded its own failure, and left the clearest surviving evidence anywhere of how the ancient Egyptians actually worked stone.
