Study methodology of the architectural periodization of Algerian mosques and the ritual role of elements (Mihrab, Minbar, Qibla, Bath for Ablution) in the Islamic worship service

The article introduces a study methodology of the architectural periodization of Algerian mosques based on the systematic structural analysis. The specificity of the Islamic architectural school of Algeria is the simultaneous combination of the traditions of many cultures, imported from other countries, and local, different within certain regions. In the cities of Algeria, mosques with different spatial organization have survived: the so-called Arabian column type, the Maghreb type, the Kharijites type and the Ottoman type. As in the Islamic world in general, a special role in the mosques of Algeria is devoted to ritual ablution.
