The Afon Dulas, or North Dulas, is a river forming the border between Merionethshire/Gwynedd and Montgomeryshire/Powys in Wales. Another river called Afon Dulas joins the Dyfi from the south, upstream of its confluence with the North Dulas: locally this is referred to as the South Dulas.
Afon Dulas rises from a source in the hills above Aberllefenni and passes through Corris, Esgairgeiliog and Pantperthog before joining the Afon Dyfi at Ffridd Gate near Machynlleth. [1]
The Dulas is recorded as an important land boundary in 1200, in a document written in 1428. This document describes the land owned by Einion ap Seisyllt, in the time of Llywelyn the Great, as "tota terra inter aquas de Dyfi et Delwas" (Latin, meaning: all the land between the rivers Dyfi and Dulas). [2]
It rises in Glaslyn, below the slopes of Foel Fadian, and passes the hamlet of Forge and Plas Dolguog before joining the Dyfi.
Close to its confluence with the Dyfi it is crossed by the Cambrian rail line on a bridge known as the Black Bridge. After the line had been repeatedly closed due to flooding after heavy rain, in 2021 it was announced that the bridge and its approaches were to be raised by a metre to try and alleviate the problem. [5] Work began on 15 May and was due to be completed by 28 June.

Llwyngwern was a station on the Corris Railway in Wales, built to serve the hamlet of Pantperthog and the residents of Plas Llwyngwern, a house where a daughter of the 5th Marquess of Londonderry lived with her husband. Although the Plas was in Montgomeryshire, the station was across the Afon Dulas in Merionethshire. The station was built at Llwyngwern, rather than at Pantperthog, because there is a very tight bend and a steep gradient on the railway at Pantperthog.
Ffridd Gate was a station on the Corris Railway in Merioneth, Wales, UK. It was built at the level crossing over the B4404 road to Llanwrin, near the hamlet of Fridd. A small hamlet also grew up around the station and a nearby (pre-existent) toll-house. The hamlet and former station are near to the confluence of the Afon Dulas and the River Dyfi, around 2+1⁄4 miles (3.6 km) west of the village of Llanwrin and 1 mile (1.6 km) north of the town of Machynlleth.
Sarn Helen refers to several stretches of Roman road in Wales. The 160-mile (260 km) route, which follows a meandering course through central Wales, connects Aberconwy in the north with Carmarthen in the west. Despite its length, academic debate continues as to the precise course of the Roman road. Many sections are now used by the modern road network while other parts are still traceable. However, there are sizeable stretches that have been lost and are unidentifiable.
