This book intends to present the development of socio-spatial practices in the metropolitan coast of the Northeast of Brazil, highlighting the main urban, spa and tourist agglomerations: Salvador-BA, Recife-PE, Fortaleza-CE, and Natal-RN. The objective is to study the processes of urbanization associated with maritime leisure. In the first chapter, the reader will find a historical and conceptual presentation highlighting the relevance of leisure practices, their forms-flows and their role in the formation of maritime resorts. The second chapter analyses the context of the northeastern region of Brazil and demonstrates the process of modernization and formation of the seaside function within the cities, and later, in the maritime metropolises of the region. The relationship between urbanization and touristic real estate ventures is the central theme of the third chapter, which proposes a specific methodology for studies of this nature. The final chapter presents the seaside resorts in the metropolitan area of Fortaleza, a case study similar to others in the Northeast, examining the urbanistic effects and the key ideas of the planners.
