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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
