In March 2017, construction workers in Cairo uncovered a colossal 9-metre quartzite statue, buried for centuries beneath mud and modern rubble.
Archaeologists quickly realized the fragments belonged to a pharaoh - likely Psamtik I - and that the site marked the heart of Heliopolis, the legendary City of the Sun.
Once one of the most sacred places in ancient Egypt, famed for its temples to Ra and its role in the earliest dynasties, Heliopolis had long been thought lost beneath the expanding metropolis.
This documentary follows the excavation team as they battle rising groundwater, collapsing pits and intense urban pressure, racing to secure and save what remains of a vanished religious and political centre. It’s a struggle to preserve a missing link to the world of Egypt’s sun-gods and earliest pharaohs.
