From quarry to finished product

From quarry to finished product

From 3 million cubic metres of blue limestone reserves at Old Leighlin, Kellymount and Holdensrath, Kilkenny Limestone annually quarries c. 75.000m³ for processing into limestone slab and its full suite of finished stone products.

Kilkenny Limestone Quarries is rooted in a fine tradition of blue limestone production. Inspired by centuries of master-craftsmen before us, we are honoured to be the principal suppliers of the stone to modern day architectural and design projects from rural Ireland to downtown Manhattan. Production of our entire blue limestone range is carried out at our Irish quarry facilities in Carlow and Kilkenny under a rigorous quality system.


First quarry

The venture which led to Kilkenny Limestone began when John Sisk & Son acquired an Irish Blue Limestone quarry near Ballinasloe, Co. Galway in response to the growing demand for native Irish stone in the building projects of the new Irish state.


Old Leighlin

As the resources at the Ballinasloe site were utilized in the construction of Galway Cathedral, the company sought to expand operations with two new quarries at Ballybrew, Co. Wicklow and Old Leighlin, Co. Carlow.


Cladding & paving

The 1970s marked a period of change in how Kilkenny Limestone was manufactured and marketed, with a move away from solely ornamental uses for the stone. We began to innovate more practical and functional applications, such as cladding and paving. A good example of work from this period is the Met Eireann Headquarters at Glasnevin, Dublin with its angled façade of blue limestone cladding.


New export channels

During an era of economic difficulties for Ireland, Kilkenny Limestone began to forge new export channels for blue limestone products, particularly in Europe, developing a strong reputation within the Dutch and Belgian markets. The operation of a Belgian subsidiary enabled us to strengthen our foothold in Europe, expanding our reach across a number of countries.


Iconic buildings

Over the last two decades, Kikenny Limestone has made continued investment, not just into the Irish market, but also within the UK. These significant strides received recent recognition in being selected as suppliers to Norman Foster’s illustrious flagship project on the River Thames – the MoreLondon Development. Stone Developments are also proud partners in the construction of many of modern Ireland’s most iconic buildings, including Department of Finance, Dublin, Lewis Glucksman Gallery, Cork and Offaly County Council Civic Offices.


Brachot Family Member

In 2011, the three quarries of Old Leighlin Co. Carlow, Kellymount and Holdensrath Co. Kilkenny were brought under one name, Kilkenny Limestone, as part of the Belgian Brachot Group.

The Story of Irish Blue Limestone

The Story of Irish Blue Limestone

The Story of Kilkenny Limestone and formation of the Irish Blue Limestone in general, begins long ago before the Ages of Man or the Age of the Dinosaurs, during what is called the ‘Age of the Crinoids’, some 340 million years ago.

In the warm, shallow, tropical seas that once extended across much of what we know today as north-east Europe, sea life and calcium carbonate crystallised over time to form the sedimentary rock with its characteristic coral strata, crinoid, brachiopod and gastropod fossils. There it remained for hundreds of millions of years until Europe’s settlers began to conceive of building robust and timeless structures. The story of this material tracks the development of civilisation in Ireland. Blue limestone was used by the Neolithic people to construct monuments in a time before the Pyramids of Egypt were first imagined.

As society developed, the stone was utilized for the more sophisticated means of carving and is seen in Ireland’s famed Celtic crosses. A technically superior building material, the stone’s elegant and timeless qualities have been consistently celebrated in Irish architecture from ancient monasteries and abbeys to the castles and houses of chieftains and lords. This is a tradition that continues through to the modern day. Fully appreciating the rarity and uniqueness of this stone, Kilkenny Limestone has dedicated itself to its correct and appropriate usage in contributing to the great buildings and landscapes of our modern age.
