Siwa Oasis is a solitary settlement that survives in the middle of the Western Desert, a breath away from the Libyan border. At the heart of the oasis stands Shali Fortress — a centuries-old stronghold built to protect the inhabitants from nomadic raids and the extremes of the desert itself. And while it looks today more like a melting sand sculpture than a fortress, it remains without question the most defining landmark in all of Siwa.
How Shali Was Born
It all began in the early 13th century, in 1203 AD. Seeking safety against the open desert horizon, the inhabitants built Shali entirely from kershef — a traditional local mixture of rock salt from the lakes and mud. This material allowed them to raise massive, thick walls that were not merely durable, but functioned as perfect insulation against Egypt's punishing sun.
Life in the Mud Citadel
For centuries, Shali beat at the heart of the oasis. An entire small city developed within its walls: dark, labyrinthine alleyways connected homes to mosques and small markets. And the fact that the entire fortress forms such a towering hill was no accident — anyone approaching across the flat, endless desert could be spotted with the naked eye from kilometers away.
The Fall of Shali
What gave Shali life — kershef — was ultimately also its undoing. Salt holds mud together, as long as it stays dry. In 1926, however, the area was struck by days of torrential rain, something almost unheard of in the desert. The water soaked through and dissolved the salt within the walls, causing massive sections of the fortress to collapse. That was the moment the inhabitants abandoned it en masse and sought safety on the flatter, lower ground surrounding the oasis.
Shali Today
Today the imposing, hollowed-out skeleton of the former fortress dominates the skyline. What's magical is that you can still get lost inside the remnants of its alleyways and, treading carefully on the hardened salt, climb all the way to its highest peak. From up there, you see the vast, lush palm groves of the oasis locked in a direct confrontation with the encroaching dunes, and the call of the imams breaking the silence of the desert.
Shali Fortress may be literally dissolving, but it doesn't feel dead in the slightest. When you slip through its half-collapsed rooms, it's easy to picture the generations of families who lived here. And when you finally stand at the summit, looking out over the empty desert below, you understand immediately why this mud city was everything to its people — and why it remains the pride of Siwa to this day.
