Lévi-Provençal, Évariste (1936), "Tangier", in Martin Theodoor Houtsma; Arent Jan Wensinck; Hamilton Alexander Rosskeen Gibb; Wilhelm Heffening; Évariste Lévi-Provençal (eds.), Encyclopaedia of Islam, vol. IV, Leiden: E.J. Brill, pp. 650–652. For more up-to-date extensive coverage of the Tangier Kasbah, the Place de la Kasbah specifically, the Dar al-Makhzen zone, Dar Zero, and other adjacent features in this area, see for instance Martin Malcolm Elbl, Portuguese Tangier (1471–1662): Colonial Urban Fabric as Cross-Cultural Skeleton (Toronto / Peterborough: Baywolf Press, 2013), preceding publications and data such as Martin Malcolm Elbl, "Tangier's Qasba Before the Trace Italienne Citadel of 1558–1566: The 'Virtual' Archaeology of a Vanished Islamic and Portuguese Fortress," Portuguese Studies Review 17 (2) (2009): 1-45, and various subsequent publications, such as Martin Malcolm Elbl, "Tangier’s Domus Praefecti (Governor’s House) and Ceuta’s Paços Reais / Paço Velho (Palacio Viejo): 3D-Modelling Vanished Prestige Dwellings and Cross-Cultural Symbols of Governance," in Martin Malcolm Elbl, ed., Encounters in Borderlands: Portugal, Ceuta, and the 'Other Shore' (Toronto / Peterborough: Baywolf Press, 2019), 177–242, or most recently, Martin Malcolm Elbl, “ ‘Tunnels Below’ (Dar Zero ~ Tangier): Urban Myths, a German ‘Baron’ from Maryland, and a Very Real Portuguese Citadel," Portuguese Studies Review 30 (1) (2022): 199-239. The publications (in English) supply abundant references to secondary sources in English, Portuguese, French, and other languages, references to archival documents and primary sources, and references to indispensable graduate theses by diverse scholars. Transcripts of unpublished documents are available in these works, as are many maps, diagrams, and photographs. The large body of data entirely supersedes the 1936 "Tangier" article, clarifies the 'Upper Castle' issue, and addresses numerous other relevant points, setting the Kasbah Palace in very detailed long-run context. Most of the relevant items are accessible on academia.edu (consulted 29 May 2023). See https://utoronto.academia.edu/MartinMalcolmElbl
