Llanrwst is a small town and community on the A470 road and the River Conwy in Conwy County Borough, Wales. It takes its name from the 5th- to 6th-century Saint Grwst, and the original parish church in Cae Llan was replaced by the 12th-century church.
Llanrwst developed around the wool trade, but also became renowned for harp and clock manufacture.Today, lying as it does on the edge of Snowdonia (Snowdonia starts about 3/4 mile away on the other side of the river Conwy ), its main industry—aside that of being a market town—is tourism.
Notable buildings in Llanrwst include the almshouses, two 17th-century chapels and the Parish Church of St Grwst, which holds the stone coffin of Llywelyn the Great. Pont Fawr, a narrow three-arch stone bridge that is said to have been designed by Inigo Jones, was built in 1636 by Sir John Wynn of Gwydir Castle. The bridge connects the town with Gwydir, a manor house dating from 1492, the 15th-century courthouse known as Tu Hwnt i’r Bont and also with the road from nearby Trefriw.In the 2011 census the population of the town was 3,323.
The River Conwy is a river in north Wales. From its source to its discharge in Conwy Bay it is a little over 27 miles (43 km) long. “Conwy” was formerly Anglicised as “Conway.”
It rises on the Migneint moor where a number of small streams flow into Llyn Conwy, then flows in a generally northern direction, being joined by the tributaries of the rivers Machno and Lledr before reaching Betws-y-Coed, where it is also joined by the River Llugwy. From Betws-y-coed the river continues to flow north through Llanrwst, Trefriw (where it is joined by the Afon Crafnant) and Dolgarrog (where it is joined by Afon Porth-llwyd and Afon Ddu) before reaching Conwy Bay at Conwy. During spring tides the river is tidal as far as Tan-lan, near Llanrwst.
