About

About Aswan First Cataract North Canal

Pharaonic–Ptolemaic granite transport canal cut through First Cataract granite bars, 2.1 km long, linking the unfinished obelisk quarry (north bank) to the Elephantine–Philae Nile channel. The 8-m wide canal with sloping granite banks, bollard niches and sledge ramps fed the obelisk, colossus and pyramidion supply chain from Aswan to Thebes and Giza. New Kingdom inscriptions (Thutmose III–Ramesses II) and a Persian Darius canal stela replica flank the northern lock-like narrowing where crews tracked granite barges. Still navigable at high water; Melinda Hartwig corpus 2012 documented 22 bollard stones.

Why it mattersGranite lifeline of Pharaonic megaliths — the only canal enabling Aswan obelisk transport through First Cataract.
