Overview
On 2 March 1825, a powerful earthquake struck Blida during the final years of Ottoman rule, causing catastrophic destruction. The shock was severe enough to collapse most of the city's structures, killing thousands of residents and leaving the walled city in ruins.
Aftermath and Reconstruction
The earthquake arrived just five years before the French invasion of Algeria (1830). The city had only partially recovered when French forces entered Blida in 1830. Colonial authorities subsequently undertook a systematic reconstruction of the urban fabric, replacing the Ottoman-era organic layout with a gridded European street plan — a decision that permanently altered Blida's architectural character.
The reconstruction period coincided with the arrival of European settlers and the transformation of Blida into a French colonial garrison town.
