The Welsh language is used alongside English in parts of Pembrokeshire, especially north of a line running through Solva (called the Landsker Line.) For this reason, some of our towns and villages have two names, one for English speakers and another used by Welsh speakers. Please be aware that there are two (or more) translations for some towns and this list only shows one popular choice.
