On the road from Llanerchindda to Cynghordy in the distance looms this fantastic Viaduct. It was totally unexpected find on my ride. The road takes you under the Viaduct, where there are various plaques. The Cynghordy viaduct, with eighteen arches built in sandstone and lined with brick, is 259 m (850 ft) long on a gentle curve, rising to a height of 31 m (102 ft) above the valley. It is a fine sight.  Still in use today as part of the Central Wales Line.

The Cyndhordy Railway Viaduct, an elegant curved structure constructed in 1868, stands as a testament to Victorian engineering prowess and remains operational to this day. As a vital segment of the Heart of Wales line, it plays host to occasional nostalgic steam trains taking tourists on scenic journeys from Shrewsbury to Carmarthen or Swansea and back. This vantage point provides an excellent panorama of the historic arches, complemented by an informative display board to delve into the fascinating history of the bridge.

Built in 1913 the Rhandirmwyn Bridge links the two sides of the Towy valley by this rivetted girder road bridge. On the southern side you'll find the Towy Bridge Inn, a lovely riverside pub.

THE TALE OF THE WELSH “ROBIN HOOD” Known as Twm Siôn Cati Twm Siôn Cati is a historically known figure in Welsh folklore. A tale recounted by Meyrick recalls how Twm was asked by a poor man to steal a pitcher for him. They went together to a merchant where Twm started belittling the man's wares. Having told his friend secretly to take the pitcher of his choice, Twm distracted the merchant by telling him there was a hole in one of the pitchers, which the man denied. Twm desired him to put his hand in the pitcher to test it and the man still denied there was a hole. Twm then asked him how, if there was no hole, could he have put his hand inside? By this time his friend had disappeared with his pitcher, undetected. A tale from Prichard's book involves an occasion when Twm is staying in an inn overnight and realises other people are planning to rob him the following day after he sets off. He has a large sum of money with him. The following morning he behaves as though his money is in the pack-saddle of his horse. When the highwayman catches up, Twm drops the saddle in the middle of a pool. The highwayman wades into the pool to fetch it, Twm takes the opportunity to make off with the highwayman's horse. A complication arises because the horse responds to the voice of the highwayman crying "Stop!" Luckily Twm, in terror, happens to shout a word which makes the horse gallop on again, and he is conveyed to safety. Another tale recounts how Twm waylaid a rich squire, who was accompanied by his daughter, Twm was so smitten with her that he returned her jewellery to her and attempted to woo her, against her father's opposition and, initially, her own. One full moon shortly after the robbery, he crept to her window, roused her from sleep, caught her hand at the window and kissed it, refusing to let her go until she promised to marry him. She wouldn't promise so Twm drew his dagger, drew blood on her wrist and threatened to sever her hand unless she assented to marriage forthwith. She agreed to marry him and she kept her hand. Their marriage followed soon after, despite her father's views and the directness of Twm's courtship methods. The girl was supposedly the widow of the sheriff of Carmarthen. Through this marriage Twm is supposed to have gained respectability, eventually becoming a justice of the peace, sitting in judgement on others, a position he held until his death aged 79.

Cynghordy Railway Viaduct is a very impressive structure if i must say. Located in a remote part of Wales Llandovery which is just north of the Brecon Beacons. Pictures don't convey the unassuming majesty of this incredible sight. To think it was constructed 150 years ago with men and horsepower is awesome. Such a incredible sight to see!! It was like something out of Harry Potter!

This attractive RSPB site has a circular footpath adjacent to a river with beautiful rock cascades and old mossy trees. It is also home to the Twm Sion Cati's cave. All worth a look off of the bike.
