The specialty papers, records that the Church dedicated to the Assumption of Mary was built between 1840-1852 right in the place where it can be seen today.
The church plan is basilically style, with towers on the nave and a porch, built of red brick with lime mortar on a stone foundation.
This stone used in the foundation of the church was taken from Giurgiu fortress walls, as we found out from an approval given by the General Kiseleff in 1832.
The construction bears the specifics of Byzantine architecture, characterized by straight lines and round circle arches, thick walls, square pillars, large windows and domes with spherical shape, having at the time of construction the specific air of the era it was built. The church undergone some changes in the first half of the twentieth century.
In 1930 the bell tower and rectory building are repaired.
The appearance the cathedral it has today it seems we owe it to the architect Penescu and the engineer Ciulei from Bucharest. They have built in 1935, in Giurgiu, the warehouses in the central square, and the Court building in Alei Park.
The original painting which adorned the walls of the old church was painted in oil, in the manner of Gh. Tattarescu decadent school by the painter Nicolae Pitaru. The mural painting existing now executed in fat tempera and Neobyzantine style, was painted by Nicolae Stoica between 1939-1959. Its restoration was carried out between 1989-2005 by Drejoi Ion Nicolae Stoica’s apprentice.
The iconostasis, performed in Baroque style with oil painting, dating from the nineteenth century, is the work of the painter Nicolae Pitaru. This was going at the beginning on the entire width of the church, covering the three apses. It consisted of twelve big icons. It has undergone some changes in the summer of 1948, by reducing its sizes to the existing ones.
It acquires the title of the cathedral from ancient times.
This title was borne with dignity until 9th of April 2006 when, by investiture of the first bishop of Giurgiu in the person of Reverend Dr. Ambrose Meleaca, the church Assumption of the Virgin Mary became an Episcopal Cathedral in the real sense of the word.
The hardships that Assumption Church passed during the years have ended on April the 9th, 2006 when, in this day of incomparable value and beauty, the Church was officially raised to the rank of Episcopal Cathedral.
