The Nativity of Christ Cathedral (Kristus Piedzimšanas pareizticīgo katedrāle) was built to a design by Nikolai Chagin in a Neo-Byzantine style between 1876 and 1883, during the period when the country was part of the Russian Empire. It is the largest Orthodox cathedral in the Baltic provinces built with the blessing of the Russian Tsar Alexander II on the initiative of local governor-general Pyotr Bagration and bishop Veniamin Karelin. The Nativity of Christ Cathedral is renowned for its icons, some of which were painted by Vasili Vereshchagin.
During the First World War German troops occupied Riga and turned its largest Russian Orthodox cathedral into a Lutheran church. In independent Latvia the Nativity of Christ Cathedral once again became an Orthodox cathedral in 1921. Archbishop Jānis Pommers, a native Latvian, played a key part in the defence of the cathedral. In the early 1960s Soviet authorities closed down the cathedral and converted its building into a planetarium. The cathedral has been restored since Latvia regained independence from the Soviet Union in 1991.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
