Orthodox architecture in the United States plays a vital role in preserving Russian cultural heritage. The earliest churches, dating to the first mission in 1794 on Kodiak Island, offer insights into the early growth of Orthodoxy in America. Churches built during the Russian America period were characterized by simple forms and layouts. The transition from the Russian wooden Empire style to neoclassicism was only partially reflected in North America due to resource limitations and short development timelines. In the 1920s and 1930s, connections to Russian architectural traditions remained but weakened, leading to the abandonment of traditional styles for eclectic and modern architectural practices. The October Revolution of 1917 and its aftermath forced believers to reorganize, changing their architectural approaches as Russian management and funding ceased. The Great Depression further reduced the scale of designs and simplified architectural plans, reducing the distinctiveness of Orthodox churches. Since the 1970s, the restoration of Eucharistic communion has ushered in new architectural changes, including the adoption of American models and a departure from traditional Russian canons. Modern Orthodox churches often reflect a mix of styles and eras, including neoclassicism and Russian motifs, yet without clear stylistic consistency. Orthodox architecture in the United States is not isolated; it interacts and competes with other faith traditions, enriching the local cultural landscape. Despite these challenges, the Orthodox Church remains an active participant in American cultural life, preserving and evolving its heritage within new conditions.
