Architectural expressions resonant with Islamic traditions appear in diverse modes across the Americas, from Andalusian-inspired colonial patios in Peru to the modern and contemporary patronage of immigrant communities in the United States and Canada. This volume examines the multiple manifestations of Islamic architecture that permeate the region’s built environment to invite an expanded framing of this architectural legacy via a hemispheric consideration of aesthetics, narrative and patronage. Chapters consider a broad range of topics from the migration of aesthetic traditions and construction techniques tied to the architectural forms of the Islamic world in the colonial ‘New World’, to the direct contributions of modern and contemporary migrants in shaping a collective identity and the built environment. By placing in productive dialogue sites that represent Islamic and Islamicate architecture across North and South America – two areas outside of the traditional conceptions of the Islamic world – this volume bridges transregional and transcultural gaps in the current literature.
