Pant Glas was a railway station opened by the LNWR in Pant Glas, Gwynedd, Wales, serving a sparsely populated rural area. Custom was never heavy, leading to goods services being withdrawn in 1952 and the station being closed in 1957, though traffic continued to pass through until the line closed on 7 December 1964 as recommended in the Beeching Report.

The Battle of Bryn Derwin was fought in Eifionydd in Gwynedd in June 1255, between Llywelyn ap Gruffudd and his brothers, Dafydd ap Gruffudd and Owain Goch ap Gruffydd Llywelyn had ruled over a truncated Kingdom of Gwynedd jointly with Owain since the death of the previous Prince of Wales, Dafydd ap Llywelyn, in 1246, but relations between the two men apparently deteriorated in the early 1250s. The battle lasted for no more than an hour, and resulted in a victory for Llywelyn; Dafydd and Owain were both imprisoned. Owain died in prison around 1282, but Dafydd was soon released and went on to play a central role in the royal government of Gwynedd until his defection and subsequent removal to England in the mid-1260s. Subsequent military campaigns by Llywelyn in 1257 and 1260 recovered much lost Welsh territory, and his undisputed leadership within Wales ushered in a period of stability that would last until the mid-1270s.

The Nantlle Valley (Welsh: Dyffryn Nantlle, IPA: [ˈdəfrɨn ˈnantɬɛ]) is an area in Gwynedd, North Wales, characterised by its numerous small settlements. The area is also historically important geologically, and featured in one of the most contentious disputes of the 19th century, between the 'Diluvialists' who believed in the Biblical flood, and the ‘Glacialists’, who supported the Glacial Theory, which was substantially established by studies of the drift sediments on Moel Tryfan.Between 85 and 90% of the population of the Nantlle Valley speak Welsh as their first language.Some of the communities came into being as a result of slate quarrying in the late eighteenth or early nineteenth centuries, and some have a history stretching back to antiquity. There are Iron Age forts at Caer Engan in Pen-y-groes and on the coast at Dinas Dinlle and evidence of Bronze Age settlement on the higher ground. The valley was important during the Middle Ages, with a clas or ecclesiastical college developed at Clynnog Fawr.The Glynllifon estate can trace its foundation historically to the 8th century and there is evidence of occupation on the site going back to the Iron Age.There were a number of quarries in the valley, the largest being the Dorothea and Pen yr Orsedd quarries. Although the major quarries are worked out, there remains demand for slate waste for garden decoration.In 1991, Antur Nantlle Cyf was established as a community enterprise to work for the benefit of the Nantlle Valley and its surrounding area.
