"Water architecture in South Asia" represents some of the most beautiful and spectacular building achievements of the region. This study provides a holistic approach to the subject, suggesting common links and regional contrasts between types of water structures and their contexts, with a comprehensive interpretation of the history and meaning of water architecture in India, Nepal and Sri Lanka. Five types of water structures are identified. Their development is traced from simple to more complex forms, considering how these accommodate secular and religious functions, and present expressions of sacred and royal authority. This publication is the first reference work on the subject. Many of the structures discussed and illustrated here have never been published before. Its comprehensive approach will have a wide relevance for other South Asian disciplines.
