Spatial Characteristics and Their Role in Evoking Spirituality in Mosque Courtyards Does the presence of a courtyard enhance the sense of spirituality within a mosque? The proposed research paper aims to answer this question by identifying the spatial characteristics that evoke a sense of spirituality within mosque courtyards. The focus on courtyards in this paper stems from two main reasons: first, the disappearance of courtyards in many modern mosques ; and Second, there is a notable gap in academic research exploring the spatial characteristics of traditional mosque courtyards and their role in fostering spirituality. These characteristics, refined over more than ten centuries, continue to influence the spatial and spiritual experiences of users in courtyard mosques to this day. The study will analyze these characteristics by examining a sample of mosques that represent the evolution of the traditional mosque prototype in Egypt over six centuries. This will begin with the Mosque of Amr ibn al-As (21 AH / 641 CE), built during the Islamic conquest of Egypt, and culminate with the Mosque of Sultan Hassan (757–764 AH / 1356–1362 CE), constructed in the late Mamluk Bahri period. The proposed sample includes the following mosques: Amr ibn al-As Mosque, Ibn Tulun Mosque, Al-Azhar Mosque, Al-Aqmar Mosque, Al-Salih Tala’i Mosque, Al-Salih Najm al-Din Ayyub Madrasa, Al-Zahir Baybars Mosque, Sultan Qalawun Complex, Baybars Khanqah, and Sultan Hassan Mosque. The study will combine behavioral analyses (using personal interviews and observations) with spatial analyses employing Space Syntax analytical tools( depth map tool). The aim is to document the spatial characteristics that foster spirituality by examining users' spatial experiences within mosque courtyards. It is anticipated that the study will result in the development of an initial matrix of these characteristics.
