PHOTOGRAPH: [The path to Manod slate quarry].

Manod quarry is located high up the slopes of Manod Mawr. A horizontal tunnel led into the mountain, intercepting the alternating layers of slate and hard rock. The slate was excavated, leaving enormous caverns separated by pillars of harder rock penetrated by the access tunnel. In a number of these caverns, chambers were constructed to house pictures from The National Gallery during the Second World War.
