This thesis explores the influence of spirituality from the Dutch East Indies on Dutch architecture from 1890 to 1920. It investigates the interplay between Eastern spirituality, particularly through theosophy, and architectural theory, focusing on key figures like K.P.C. De Bazel and J.L.M. Lauweriks. Through an analysis of influences from the Theosophical Society in both the Dutch East Indies and the Netherlands and architectural works, it reveals how Hindu concepts and Indo culture were translated into architectural forms. While some projects demonstrate a clear integration of spiritual concepts, others reflect a superficial borrowing of aesthetic elements. The study provides an examination of the relationship between Eastern spirituality and Dutch architecture, shedding light on a lesser-explored aspect of architectural history and offering insights into the cultural exchanges between the Dutch East Indies and the Netherlands during this transformative period.
