The Holy Trinity Cathedral (Serbian: Саборни храм Силаска Светог Духа на Апостоле, Saborni hram Silaska Svetog Duha na Apostole) is the seat of Eparchy of Niš.

[1] The Niš Cathedral, both in terms of its architecture and the icons made for the iconostasis, occupies an important place in the Serbian history of art.

Different stylistic motives are present on the church: Serbian-Byzantine, Romanesque-Byzantine and Islamic architecture, but also Renaissance and Western Baroque.

The following year, more precisely on May 12, 1857, the municipality concluded a contract with the architect Andrey Damyanov from Veles on the construction of a three-nave basilica with five domes.

The solemn consecration was performed only after the liberation of Niš on February 13, 1878, on the day of St. Simeon, with the presence of Metropolitan Mihailo of Belgrade and Prince Milan Obrenović.

Of great value is the shroud from the beginning of this century, made of white silk and gold wires, encrusted with lace.

The way the church was built caused a lot of problems, so the temple, only twenty years after its construction, had to be repaired several times.

Since it was built during the Turkish occupation, according to the rules of the time, the bell tower was not allowed to be higher than the roof of the church.

[5][6] The cause of the fire has not been clarified yet, but it is speculated that it is a matter of negligence, because the works on installing underfloor heating have been carried out for more than a year, which was financed by donations from Greece.
