Cegin Viaduct

The Cegin Viaduct is a monument of international importance, believed to be the oldest known multi-arched railway bridge to survive above ground in Wales, and possibly the world. Constructed between 1798 and 1800, it was crucial for the Penrhyn Railroad, transporting slate from local quarries to Porth Penrhyn for global shipment. Its excellent preservation offers valuable insights into early railroad construction techniques and the region's rich industrial heritage.
