Pirita Convent. The History of the Construction and Research is a scholarly monograph that delves into the architectural and historical significance of the Pirita Convent ruins in Estonia. The work meticulously examines the construction phases of this unique double monastery, the socio-religious context of its establishment, and its eventual destruction during periods of upheaval. Drawing upon limited archival sources, the authors reconstruct the post-destruction narrative of the site. The book also highlights the extensive archaeological excavations conducted between 1975 and 1980, which were pivotal in the conservation efforts of the ruins. Furthermore, it discusses the modern revival of the Brigittine tradition through the establishment of a new convent complex adjacent to the historical site, emphasizing the enduring legacy of the order.
