The foundation of the Church in honor of the Three Saints was providentially connected with the opening of the Tauride Theological Seminary in Simferopol. The first intercessor before the Holy Synod on its opening was Bishop Alexis (Rzhanitsyn). But due to the lack of funds the idea did not materialize.
Archbishop Gurii (Karpov), who replaced Bishop Alexis on the Crimean cathedra, now ranked among the saints, provided the necessary materials to the Holy Synod, which after their consideration determined: «The opening of the Tauride seminary to be carried out gradually over a period of 6 years, beginning in the second half of 1870». On May 30, 1869, Emperor Alexander II signed the permission to open the Tauride Theological Seminary in the Crimea.
The seminary building was ceremonially laid on April 11, 1871. The building was designed by the provincial architect K. N. Eremeyev and engineer V. A. Grachev. The construction was led by contractor N.A. Masyakhin, a merchant of the I guild of Sevastopol, known in Simferopol for building churches, gymnasium, orphanage.
As the importance and role of the Tauride Theological Seminary strengthened, there was a need to build a large, independent, freestanding seminary church.
In 1900, July 18, in honor of the 25th anniversary of the seminary such a church was laid. In August 1900, A. I. Karapetov, a junior architect of the Tauride Governorate Board, submitted a project and estimate of the church to the seminary board. The contractors were offered to Nikolai Solovyov, a well-known church builder in the diocese, a Berdyansk merchant.
The work was started in February 1901 and completed in September 1903. The Church of the Three Saints was consecrated on September 11, 1903.
The Church of the Three Saints is five-domed: four small domes are located on low turrets at the corners of the central part. The hipped roof passes into a light drum, graceful, slender with eight arched windows. It is crowned by the main dome with a cross.
In the same year the seminary inspector R. Sokolov made a description of the church and its interior, which has survived to this day and contains the following information:
«The newly rebuilt seminary church is a high and very beautiful basilica on the type of ancient Christian churches… Inside the temple, the altar part is raised above the middle part on two steps and enclosed by an oak iconostasis, executed at the St. Petersburg factory of Zheverzhev….
The middle part of the church with a high arch supporting the dome is divided into two naves. About each side of the arch from the west are placed the best icons of the old temple. The walls of the temple in the middle part are still insufficiently filled with icons.
Painting of the latest mixed style, which combines the strict features and beauty of the old Byzantine writing with the technical methods of the new style.
The paintings of the seminary church were done by the artist Dmitry Pravednikov. He also did the paintings of the Ecclesiastical Men’s College in Simferopol…».
Prominent figures of the Russian Church prayed in the Trisvyatitelsky Church: the confessor of the royal family (Emperor Nicholas II) Bishop Theophan of Poltava (Bystrov), who headed the Crimean cathedra in 1910-1912;
о. Sergius Bulgakov, philosopher, future professor at the Theological Institute in Paris, who taught at the Tauride seminary in 1919-1920, the last rector of the theological seminary Archimandrite, later Metropolitan, Venimamin (Fedchenkov) — a famous hierarch of the Russian Orthodox Church, ardent patriot of his Fatherland, spiritual writer, who left readers vivid images of Crimean righteous people, whom he had the opportunity to observe during his stay in Crimea.
After the revolution and the seizure of Crimea revolutionary troops in November 1920, the order of the Crimean Revolutionary Committee on the restructuring of educational institutions Tavricheskaya Theological Seminary was closed. In 1922 was closed and the seminary church. In the 20-ies the church was deprived of domes, lost wall paintings, as well as high artistic value oak iconostasis. The courtyard bell tower was destroyed. For many years the church was used for other purposes, and recently it was used as an archive.
In 1989, the Church of the Three Saints was handed over to the Simferopol and Crimean Diocese and services were resumed there.
In 1997 in the building of the Tauris Seminary was opened pastoral spiritual school of the Simferopol and Crimean Diocese. The Trinity Church regained its original purpose — to be a house of prayer for students and pupils.
Since 2007, the temple returned the status of seminary. Now, under the rector of the Tauride Theological Seminary, Metropolitan Lazar of Simferopol and Crimea, the students of the seminary offer daily prayers before the Throne of the Lord Almighty.
In 2008, the temple was restored.
