Not being Welsh, or knowing anything about this apart from what Google tells us, we are guessing this is what is now known as the Llangollen Town Weir and not Horseshoe Falls, which is further away on the same river.  If we’re wrong, please let us know … but this heavily handled and well-loved old 1951 Valentine’s postcard 7670, with 2d stamp and postmark, craftily calls it “The Weir at Llangollen”.  Grade: 2
