The complex of the Holy Spirit church and adjacent monastery was established in 1567. The construction was ordered by the King of Lithuania-Poland Wladyslaw Vasa. By the end of the 16th century, a monastery, a school and a printing shop were situated next to the church. In 1749 the church was badly damaged by fire.
After the reconstruction between 1749-1753 (made by architect January Kristof Glaubic) the church became the only Baroque style Orthodox sanctuary in Lithuania. The interior was crowned by a wooden iconostas resembling the Catholic altar, under which a crypt was built for the relics of Orthodox saints Anthony, John and Eustatius. In 1853 the relics were relocated to a new reliquary. The last reconstruction of the church was accomplished on the initiative of N. Muravyov. The monastery complex comprises two monasteries: the friary of Holy Spirit (built at the intersection in the 15th and 16th centuries) and the convent of Holy Mary Magdalene (built in the late 16th century). Both buildings (reconstructed in the 19th century) have Gothic fragments.
Today Holy Spirit church is the main Orthodox Church in Lithuania. The male and female monasteries next to the church are the only working Orthodox monasteries in Lithuania.
References:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
