Patriarch Alexius II and received donations from across Russia. The church is a 15m-high wooden structure built in traditional Russian style. It can accommodate up to 30 worshippers. The structure was built out of Siberian Pine by Altay carpenters led by K. The iconostasis of the church was created by Palekh painters. The church bells were commissioned by the descendants of Sergey Muravyov-Apostol. The church is manned year-round by one or two Orthodox priests, who are hieromonks of Troitse-Sergiyeva Lavra volunteering for the Antarctic assignment.

Among the priests’ tasks is praying for the souls of the 64 Russian people who have died in Antarctic expeditions and serving the spiritual needs of the staff of Bellingshausen Station and other nearby stations. Besides Russian polar researchers, the church is often visited by their colleagues from the nearby Chilean, Polish, Korean, and other research stations, as well as by tourists. For the benefit of Latin American visitors, some church services are conducted in Spanish. On occasion, the priest baptizes new adherents of Christianity in the Southern Ocean. On 29 January 2007, the priest of the church celebrated what was probably the first ever church wedding in Antarctica. In 2016 Patriarch Kirill visited the church. When not busy with church work, priests assist with the general maintenance of the Bellingshausen station.
