Y Dre' Newydd (‘the new town’), also known as the Anglesey Barracks is a single storey double row of slate built barracks facing built in the1870's. The best-surviving barracks within the Dinorwic Quarry. Dinorwig Quarrymen travelled from Anglesey and many other communities in Gwynedd. The Anglesey Barracks housed quarrymen unable to return home each night and were in service until 1937.

The east face of Elidir Fawr is it's finest feature, cliffs that drop into the Marchlyn Mawr reservoir. Best seen from the rocky climb up to Mynydd Perfedd.

Poor Elidir Fawr! It has been bashed about and big lumps knocked out of it at Dinorwic Quarry, it has had a power station built inside it, and has a reservoir for that reservoir almost at the very top. Fortunately when you climb it from Nant Peris you will only see the reservoir, the rest of the damage is ot of sight.
