Chester (Welsh: Caer) is a very pretty and historic English city on the river Dee, and capital of the North-Western county of Cheshire. Although maybe not worth a whole holiday, it's well worth a day or overnight trip to see the Roman ruins and medieval city centre. This fine city is also the gateway to North Wales, standing as it does directly on the border with the principality.
Chester originated in the Romano-British period at the latest, when it formed the settlement known as Deva or Castra Devana, the fortress city of the 20th Legion (Legio XX Valeria Victrix). As a result some parts of Chester are around two thousand years old. It was a Royalist stronghold during the English Civil War in the 1640s, and along the walls one can see the tower from which King Charles I watched his troops do battle.
