The Ketchaoua Mosque is a magnificent Islamic shrine located in the heart of the capital of Algeria. It sits in the historic Casbah district at the foot of the ancient fortress and is one of the most recognizable symbols of the city of Algiers. This unique architectural structure is an exquisite synthesis of Moorish and Byzantine styles, drawing attention with its elegant forms and rich history.

The building possesses exceptional aesthetic value, combining strict forms with the grace of ornamentation.
Due to its significance and preservation, the Ketchaoua Mosque is included in the UNESCO World Heritage list as part of the Casbah ensemble. It serves not only as a place of prayer but also as an important monument telling the story of the region's Ottoman heritage and its complex journey through the centuries. Visitors consistently give this attraction high marks for its grandeur and special atmosphere of antiquity.
