CAMBRIAN SLATE AWARDED GLOBAL HERITAGE STONE RESOURCE STATUS

Cambrian-age Welsh slate, which is produced at Welsh Slate Ltd’s Penrhyn quarry in North Wales, has become the first slate in the world to be designated a Global Heritage Stone Resource (GHSR).

Cambrian-age Welsh slate, which is produced at Welsh Slate Ltd’s Penrhyn quarry in North Wales, has become the first slate in the world to be designated a Global Heritage Stone Resource (GHSR).

Its designation by the International Union of Geological Sciences (IUGS), which represents the national geological societies of 121 countries, recognises its importance to the architectural heritage of the many countries in which it has been used in the past and continues to be used today.

It easily met the prestigious GHSR criteria of having a cultural history encompassing a significant period, been utilised in significant works, and widely used in numerous countries.
Cambrian Welsh Slate has been quarried in Wales for almost 2,000 years, has been utilised on major heritage projects, and been used throughout the world.

It was proposed for GHSR two years ago by the Welsh Stone Forum, supported by the Stone Roofing Association (SRA), Gwynedd County Council, the Snowdonia National Park Authority and Welsh Slate (Ltd).

Designation was awarded by the international Heritage Stone Task Group (HSTG) of the IUGS, which was formed to safeguard natural stone heritage by establishing, approving and maintaining the new international geological designation - the GHSR and associated Global Heritage Stone Province (GHSP).

Natural slate expert Terry Hughes, Former Technical Manager with Welsh Slate and chairman of the SRA, said: “We were a supporter of the GHSR concept from its inception. It has been a long haul writing the proposal at the same time as the designation scheme was being developed. We are now delighted that the importance of quarrying and the continued production of Welsh Slate especially, has been recognised. All too often the public forget that almost everything they use which isn’t a plant probably came out of the ground.”

Cambrian Welsh Slate has been used on Buckingham Palace, the Royal Pavilion in Brighton and the British Library in the UK; The Royal House, Copenhagen, Hotel de Ville, Paris and Dublin Castle in Europe; the Shaker Museum and Boston airport in America, Christchurch Arts Centre in New Zealand, and Government House [Perth, pictured] and Sydney Supreme Court in Australia.

GHSR designation seeks international recognition of natural stone resources that have achieved widespread utilisation in human culture. It aims to promote greater prominence for natural stone as used in artistic and architectural masterpieces and heritage building as well as routine historic stone applications.

Designation will also enhance recognition of natural stone among geologists, engineers, architects, heritage professionals, stone industry managers and other groups that work with stone. Additionally, it will offer a mechanism to formalise the characteristics of natural stone material for professional purposes and assist international co-operation into the research and utilisation of natural stone.
