Portmeirion is a fantasy village in North Wales created by architect Clough Williams-Ellis from 1925-1976. It has no other purpose than as a place of enjoyment, where you can just wander about, have something to eat, attend an event, or stay. There is an Italian feel to the village, which has mostly been constructed from scratch but which also includes structures moved from other locations. It was made famous as the setting for the 1960s TV series, 'The Prisoner'.
Note - dogs are not welcome, except guide dogs. Children are allowed in, though.
