A regeneration project by Caernarfon Harbour Trust and Galeri Caernarfon Cyf.

Cei Llechi


Historically, Cei Llechi (Slate Quay) was a very important industrial and shipping hub for Caernarfon and the surrounding area. The buildings had deteriorated, and now in 2022 – what were shells of buildings have been transformed into 19 workspaces for local artisan / craft manufacturers and restaurant. The site also includes 3 self-catering holiday lets, the Harbour Office’s boardroom is available to hire and an interpretation area sharing more information about the importance of Cei Llechi historically locally, nationally and internationally.

About Us


Evidence of the origins of Cei Llechi can be found as far back as 1611, where according to maps, it appeared to be a levelled area with a face cut into the bed-rock on the east bank of the river Seiont. Eighteenth century views of the area such as Richard Wilson’s painting Caernarfon Castle (1745) also depict various activities such as netting and boat-repair taking place in this area.


The project’s architect was Purcell, and Grosvenor Construction Ltd of Kinmel Bay were the main contractor responsible for the conservation and development of the site.

Work on the site started in October 2018 and the project was completed in Summer 2021.

The units/workshops are suitable to makers of all kinds – the only essential factor is that everything sold in the units are made on the site – from raw material to the finished product.

Cei Llechi offers a perfect location for any business who creates/manufactures products of all kinds – metal, glass, jewellery, wood, textiles, art, food or drink.
