Looking back at the massive Caernarfon Castle from the southern side of the river Seiont, you can imagine slipping back into a time when the castle was by far the largest building for miles around, only the church spires are taller. There are a few 3 and 4 storey Georgian houses peeping through the trees but its a scene that could be hundreds of years old, with the sprawl of the modern town out of sight and no vehicles.
