St. Nicholas Cathedral is the primatial cathedral of the Orthodox Church in America. The original parish church was founded in 1930 as the Russian Orthodox Church of Saint Nicholas. In 1949 the Synod of Bishops authorized the parish to be the church's National War Memorial Shrine and a national campaign to build a monumental Orthodox church in the capital of the United States was begun. The property upon which the cathedral is built was purchased in 1951. The substructure (basement) was completed in 1954 and was used for church services until the superstructure was completed in late 1962. A bell tower commemorating the millennium of Christianity in Russia was dedicated in 1988.
The cathedral architecture is based on the 12th century St. Demetrius Cathedral of Vladimir, Russia. Beginning in 1991, dedicated iconographers from Moscow led by Alexander Maskalionov painted icons throughout the nave in the traditional style. This work was completed in 1994.
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.
