Built on an area of 1,542 m2, it has 11 towers, of which the central one has a height of 90.5 m, making it the second tallest church in Romania, after the People's Salvation Cathedral in Bucharest.

At the initiative of the parish of Cetate (the historic center of Timișoara), a fund for the construction of the new church was set up and an appeal was launched to parishioners for donations.

The City Hall provided all the bricks free of charge, and the Reșița Steel Works made a 30% discount on the purchase price of 330 tons of iron.

On 20 December of the same year, a solemn service was held, laying the foundation stone of the future cathedral (which was consecrated by Bishop Andrei Magieru of Arad).

During World War II, after Romania turned its weapons against Germany, German aircraft bombed Timișoara (30–31 October 1944).

The building's style is neo-Moldavian, based on Romanian Orthodox, late Renaissance, Ottoman and Byzantine architecture elements, such as niches under the eaves, ribbed star vaulting in the interior and lacquered discs in a variety of colors.

The seven bells, cast in Anton Novotny's workshop, have a total weight of 7,000 kg and were made of an alloy of metals brought from Indonesia (Sumatra and Borneo).

The iconostasis was carved and gilded in 22-carat gold by master Ștefan Gajo,[9] who also made the three chandeliers, the two candlesticks and the Lord's Tomb (located in the pronaos).

The exterior walls of the church are clad in apparent red and yellow-orange brick, as well as glazed discs and painted niches.

[2] The towers are covered with glazed tiles, made in Jimbolia, which contain the colors of the national flag (red, yellow, blue) on a green background.

[12] The entrance doors, the rows of chairs and the entire furniture along the sides of the naos and pronaos are the works of the sculptor Traian Novac.

[11] The floor of the church made of mosaic tiles combines the style and color of the Banat carpets, being executed according to the sketches of the painter Catul Bogdan [ro].
