The monument comprises the remains of Cableways or 'Blondins' which were used extensively in the deep slate quarries of the Nantlle Valley and elsewhere in N Wales from the turn of the century. Those at Pen-yr-Orsedd are particularly important as the last examples in Wales to survive in situ and are located around an active slate quarry. Three of those remaining have been selected for scheduling because they are good examples, are reasonably secure and, together with the engine house for the fourth Blondin, represent an important group of associated structures. The southern two are complete with their pylons, lifting and control mechanisms, stay anchors, engine houses and power units (vandalised). The third Blondin with its pylon, cables and anchor points is also scheduled as well as the engine house for the fourth Blondin (pylon now unstable). This engine house includes the winding mechanism and a rare Ingersoll-Sergeant compressor.
The monument is of national importance for its potential to enhance our knowledge of early 20th century industrial practices. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits. The structure itself may be expected to contain archaeological information concerning chronology and building techniques. An industrial monument may be part of a larger cluster of monuments and their importance can further enhanced by their group value.
The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
