Schools/Clubs & Group Visits

Inigo Jones Slate Works was founded in 1861 primarily to prefabricate school writing slates. Today the company uses the same raw material, namely natural Welsh Slate to prefabricate architectural, memorial and craft products.

The Slate Works is now also a visitor attraction, offering the public a rare insight into the industry and how slate is worked and made into architectural items such as sills, copings, steps and kitchen work tops.  Visitors can also see how contemporary methods are used to produce plaques and nameplates.


    The Great Slate Tour (a self guided tour) lasts around one hour and includes an introductory film.

The Great Slate Tour - Self Guided Tour of the Welsh Slate Workshops    Accompanied by commentary provided on a personal Audio Device, work your way around the Slate Works, in and out of various exhibitions at your own pace.

    There are Geological, Historical, Calligraphy and Letter cutting exhibitions which are both interesting and educational. Have a go at Calligraphy and Letter Cutting on a small piece of slate that is supplied, and take it home as a souvenir!

    For children there is also a fun quiz with a slate prize to be won.
