This research paper focuses on three archaeological monuments that emerged from Sri Lankan society. By exploring the cultural biographies of these monuments, we aim to understand the local socio-ecological systems and the foreign influences that shaped them. Cultural biographies of physical objects arising from traditional roots symbolize the cultural heritage of people, embodying their desires, memories, and beliefs, which contribute to the social definition and future trends of society. This examination will elucidate how these monuments reflect the intersection of local traditions and external impacts, providing insight into the broader cultural and historical narratives of the region. By delving into the historical contexts, construction techniques, and symbolic meanings associated with these monuments, we reveal the dynamic processes through which local communities adapted and integrated foreign elements into their cultural fabric. This study contributes to a deeper understanding of the role of material culture in shaping social identity and continuity, highlighting the intricate interplay between indigenous heritage and external influences. Ultimately, this research underscores the importance of preserving and interpreting archaeological monuments as vital components of our shared human history.
