Description
Inigo Jones Slate Works
A well-known landmark site, steeped in history, and situated on a busy road.
This significant site, measuring some 2.9 acres includes a range of traditional workshops and stores, a modern show room and visitor centre, café and farm shop, and benefits from extensive visitor car parking. The site is accessed directly off the A487, some 5 miles from Caernarfon and approximately 1 mile from the settlement of Penygroes. The A487 is the main North-South trunk road and has many vehicles a day passing at this point. The property also adjoins Lon Eifion, the section of the National Cycle Network connecting Caernarfon with Bryncir. This significant site offers potential for both a continuation of the current business as well as opportunities for diversification and redevelopment.
Founded in 1861 on the grounds of a former sawmill, Inigo Jones Slateworks originally started crafting school writing slates. Since then, the company has flourished, diversifying its products to include slate architectural items, memorials, and gifts crafted from indigenous Welsh slate which are transported across the UK and further afield. The slate works has become a beacon of tourism and education; visitors can embark on self-guided tours, immersing themselves in the exhibitions which showcase geological phenomena, historical connections, intricate artistry, calligraphy, and letter cutting – all associated with the slate industry. On-site amenities, open to passing trade, include a showroom and visitor centre offering a showcase of local crafts, a popular café and a farm shop (tenanted until 2025) offering fresh produce.
