Caldicot has always been an important transport point.
It was on the Roman road from Gloucester to Caerleon, hence the growth of nearby Venta Silurum, the largest civilian settlement in Roman Wales. And these days, it's the first town visitors see when they arrive in Wales via the Second Severn Crossing.
But don't pass through; stop and take a closer look at town and country. After all, it was important enough to be mentioned in the Domesday Book.
The Caldicot Levels are a stretch of estuary flats which reach from the Usk estuary to the Severn bridges, hosting an abundance of birdlife and 50 centuries of human archaeology.
And tucked away on the edge of the town is a real gem. Caldicot Castle sits amid 55 acres of country park. Norman in origin, converted in the 19th century into a Victorian family home. And offering today's visitors a packed events programme, from outdoor theatre to medieval re-enactments.
See the town website for more on visiting Caldicot.
