To be exhibited in the Cathedral's Chapter House over the next four weeks to dazzling display of liturgical pieces is part of the annual Irish Walled Towns Network celebrations as well as Craft Northern Ireland's August Craft Month and major 'Silver Trail' exhibition happening throughout Northern Ireland.
Although the pieces housed at St Columb's have always been available for private viewings this is the first time that all the pieces can be viewed together by the city's public and tourists alike.
Dean of St Columb's, William Morton told the Sentinel: "We are absolutely delighted to have been able to do this."
Reverend Morton paid tribute to the Economic Development Office of Derry City Council for providing the state of the art secure glass cabinet that allowed the exhibition to proceed.
Pointing out the significance of the various pieces on display Dean Morton revealed that amazingly all of the silverware is still in use for services within the church.
Foremost amongst the collection is the 'Promise Chalice'. Hallmarked in 1612 it is a silver chalice and paten sent to the city by The Honourable The Irish Society in 1613, 'promising' to build a new Cathedral for Londonderry.
Also on display are a Pair of Flagons, that were the main feature of an edition of the Antiques Roadshow a few years ago. Dating from 1655, and made in Dublin, they were the only pieces of hallmarked silver made in Dublin in that year. According to the BBC antiquities experts they were extremely rare and there was general disbelief that they are still in use.
At the launch of the exhibition Mayor of Londonderry, Councillor Gerard Diver said: "Derry City Council is proud to support this important exhibition that catalogues the history and contribution of the Cathedral to the City through its unique collection of silverware."
The exhibition will run until Saturday, September 13, (9-5pm excluding Sundays) and is funded by the Heritage Council of Ireland, supported by Derry City Council.
