Llanymynech
Llanymynech is a village straddling the border between Montgomeryshire/Powys, Wales, as well as Shropshire, England, regarding 9 miles (14 kilometres) north of the Welsh community of Welshpool. The name is Welsh for "Church of the Monks". The town gets on the financial institutions of the river Vyrnwy, and the Montgomery Canal passes through it. The boundary runs for the most part along the frontages of the structures on the east (English) side of the town's major street, with the eastern fifty percent of the village in England and the western half in Wales. The Church of England parish church of St Agatha lies simply in England, although the whole village hinges on the same clerical parish. The boundary likewise passed right through the currently closed Lion club, which had two bars in Shropshire and also one in Montgomeryshire. At one time Welsh regions were described as "damp" or "completely dry" relying on whether people might drink in clubs on Sundays. When Montgomeryshire was dry it was lawful to drink on Sundays in the two English bars of the Lion but not the Welsh bar. 2 of the remaining open bars in the village are completely in England and the third is completely in Wales. Just to the north of the town is Pant. More north is the English market community of Oswestry. The English part of the town remains in the civil parish of Llanymynech and Pant, and also in the electoral ward of Llanymynech in Shropshire. This ward had a population at the 2011 census of 3,988.
