The architect Thomas Drew was the first to draw serious attention to the importance of the church, architecturally and historically, in 1866.
He produced detailed plans of the church for which he won an award from the Royal Institute of Architects of Ireland, carried out excavations and drew up a paper on the church and its history.
In a booklet published in 1873 the rector Alexander Leeper urged reroofing and restoration of the church.

In the 1980s an extensive restoration of the tower and bells was carried out.
A few years later St Anne's chapel, which had lost its roof and many monuments, was re-roofed and converted to a visitor reception centre, which included an exhibition on the history of the church.

During conservation works starting in 1996 an extensive excavation of a small section of the church was carried out, which cast new light on the early days of the church.
This contributed greatly to an understanding of the building history of the church.
The detailed results of this study were published in book form in 2006.
