[1] Built in 1921–1922, the cathedral was ready in time for the coronation of King Ferdinand and Queen Marie as monarchs of Greater Romania on October 15, 1922.

[2] Similarly, the exterior decorative elements, such as niches, beads about the column capitals and arcades, as well as the domes, resemble those found in Wallachian churches from the time of Matei Basarab and Constantin Brâncoveanu.

The interior fresco painting, by Costin Petrescu and his apprentices, follows the dictates of traditional Byzantine Orthodox iconography while exhibiting Western influences.

[2] The tall nave is dominated by a cupola painted with the image of Christ Pantocrator and held up by four octagonal columns coated in Moneasa marble.

[1][5] The western wall of the nave has paintings of clerics from the time when the cathedral was built: Nicolae Bălan, Metropolitan of Transylvania, and Miron Cristea, Patriarch of All Romania, as well as votive portraits of King Ferdinand and Queen Marie.

[5] In front of the carved and painted oak iconostasis and adjacent to the triumphal arch, there are large portraits of former Metropolitans of Transylvania Ilie Iorest and Sava Brancovici, as well as of the monks Visarion Sarai and Sofronie of Cioara, and the martyr Oprea Miclăuş of Sălişte, all of whom were canonized in the cathedral in 1955.

[5] The cathedral lies on a rectangular lot which has four pavilions, one in each corner, linked by galleries that recall those found in monasteries, formed of open double arcades held up by columns.
