The thesis consists of a translation of chapters pertaining to the construction and reconstruction of the famous St. Petersburg Anichkov and Beloselskiy-Belozerskiy palaces, detailing the founders, owners, and architects who designed and built them. These translations contain extraordinary and insightful information regarding the development of architectural St. Petersburg. The translated chapters also document the many changes that took place over time with each new resident of the palaces and outline the artistic architectural features of each palace. A preface to the thesis details the research and problems encountered in the process of translation. This annotated and photo-illustrated translation describes the architectural innovation inherent in the construction of each palace and illustrates the current state of restoration. The significance of the translated chapters lies in the fact that they contribute important cultural and historic information to English-language readers about the architectural history of St. Petersburg in its three-hundredth year.
