The Slate Landscape of Northwest Wales

If accepted it will join sites such as the Taj Mahal, the Grand Canyon, Vatican City, the Great Wall of China and Machu Picchu and will become the UK’s 33rd UNESCO World Heritage Site.


The Slate Landscape of Northwest Wales

The story of Welsh Slate is everlasting. This post-industrial landscape holds a special place in the hearts and minds of the people who live here. The North West Wales Slate Landscape tells the grand story of the evolution of a quiet, agricultural area into an area where there was no escape from the slate industry; where quarries, towns and villages appeared, and transport links carving their way through Snowdonia to the ports on the coast.

Gwynedd Council is leading on the quest to secure a UNESCO World Heritage Site for the North West Wales Slate Landscape, by working with a range of public, voluntary and private sector partners.

World Heritage Site status is an opportunity for communities, organisations and businesses to benefit from international recognition to market the area at home and abroad. It is an incentive to develop new products and services to attract and serve new customers and markets, as well as raising local pride and understanding of our rich heritage.
