Work on the bell tower and spire began on 13 August 1900, with the building contract awarded to Courtney and Co from Belfast.

In May 1964 a temporary wooden altar was placed in the sanctuary to accommodate the mass being said in English and facing the congregation.

[2] In 1984 fundraising began for the renovation work to the cathedral, which its main structure was over a hundred years old and in desperate need of repair.

From 1984 until 1988, exterior renovation work took place on the cathedral with the extension of the sacristy and the building of a brand new conference room.

The cathedral's brand new interior was opened and consecrated by the then Bishop of Derry, Edward Daly on 17 December 1989.

Details of the refurbishment and renovation work which would be undertaken in the cathedral in the coming months ahead was outlined in their parish bulletin.

The damp entering the aisle wall at the choir is causing large sections of internal plaster to boast.

On entering the porch you are now greeted by eight newly positioned oak statues of Saints Columba, Patrick, Matthew, Mark, Luke, John, Mary and Joseph.

Irish President Michael D Higgins, Deputy First Minister Martin McGuinness and representatives of the Queen, the British and Irish governments and City of Derry dignitaries, including Deputy Mayor Jim McKeever, were also present.

The sitting mayor alderman Hillary McClintock from the DUP didn't attend the funeral due to unforeseen circumstances.

The current bishop of Derry, Most Reverend Donal McKeown, was the celebrant of the Requiem Mass, which was concelebrated by the Primate of All Ireland, Derry-born Archbishop Eamon Martin, retired archbishop of Armagh Sean Brady, other bishops and clergy from across the Derry Diocese and around Ireland.

[16] The area which was the old confessional rooms since 1989 was converted into a new side chapel dedicated to Saint Mother Teresa of Calcutta.

The new chapel was blessed and dedicated by the Bishop of Derry, Donal McKeown, during the cathedral parish's annual nine-day Novena to Saint Therese of Lisieux.

On Friday 12 May 2017 at a special prayer service at 7:30 pm in the cathedral, parishioners and clergy were joined by nuns from Mother Teresa's order, who joined the packed congregation in the cathedral for Evening Prayer and a special dedication ceremony for the new chapel.

By the late 1990s, this organ had fallen into only sporadic use, with the main Sunday services being accompanied by a Johannus electronic instrument located in the south aisle.

The bells of the cathedral can be heard over the Derry area each day at 8:00am, 12:00pm, 6:00pm and 9:00pm, ringing out seasonal tunes and calling parishioners to masses.
