Manod Mawr

Manod Mawr is a mountain in North Wales, part of the Moelwynion range. It sits just outside the Snowdonia National Park near Blaenau Ffestiniog. The mountain has two summits: the main Manod Mawr and the smaller Manod Mawr North Top. The area was heavily quarried in the past, with the closed Graig Ddu Quarry located between the two summits. The North Top narrowly missed inclusion in the national park’s protected zone. During the Second World War, the mountain’s tunnels provided a hidden shelter for valuable paintings from London’s National Gallery. The artworks were stored safely in secret to protect them from wartime risks. This unusual wartime role gives the site historical significance beyond its natural landscape. The quarries and tunnels remain visible reminders of the area’s industrial past. Visitors find a rugged upland setting with open moorland and rocky outcrops. The contrast between the wild summit and the abandoned quarry workings adds to the landscape’s character. The views stretch across the surrounding hills and valleys. The site offers a quiet, remote experience away from busy tourist routes. Its wartime history and industrial scars make it a place of quiet reflection.
