Siwa Oasis is a remote settlement in Egypt’s Western Desert, near the border with Libya. At its center is Shali Fortress, a centuries-old stronghold built to protect the Siwan people from attacks and the harsh desert. Though mostly in ruins today, it remains one of Siwa’s most important landmarks.
The Birth of Shali Fortress
In the 13th century, the inhabitants of Siwa built Shali Fortress to protect themselves from raiding tribes and the exposure of open desert. Constructed in 1203 AD from kershef — a local mixture of salt and mud — the walls were dense enough to keep out the heat and hold together under desert conditions.
A Bustling Desert Citadel
For centuries, Shali was the center of Siwan life. Narrow alleys connected homes, mosques, and markets within its walls. The elevation was deliberate — anyone approaching across the flat desert could be seen from a long way off.
The Decline of Shali
Kershef was also Shali's weakness. In 1926, an unusually heavy rainstorm saturated the salt-based walls. Large sections collapsed. Most residents left the fortress after that and moved to settlements on lower ground.
Shali Today
The skeletal remains of Shali still stand. You can walk through the crumbling passageways and climb to the summit, where the palm groves and the encroaching desert sit side by side below you.
Preservation Efforts
When I was there, parts of the fortress were cordoned off. A local told me conservation work had been ongoing for years — stabilizing walls, slowing the salt erosion. It's slow going. The material that built Shali is the same material undoing it.
Shali Fortress might be crumbling, but it still feels alive. Walking through its narrow paths, you can imagine the families who once lived here, the markets, the daily life. Standing at the top, looking out over Siwa, it’s clear why this place mattered—and why it still does.
