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:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
