There is no place name in Wales that uses all 26 letters of the alphabet.
You are probably thinking of the longest place name: Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogochuchaf
Can you be a little more precise? Where is it located in Wales, for instance? Or, perahps, a little information of what context led you to ask? If it helps explain the confusion in finding an answer for you, whilst there are only five cities in Wales - Bangor, Cardiff, Newport, St Davids (also currently the smallest city in Britain), and Swansea - none of which has 9 letters - St Davids is actually little more than a village but as it boasts a cathedral it qualifies as a city and was formally granted a charter as such by The Queen. So the term term 'town' might apply to a small village which means there are likely to be many towns or villages with 9 letters in its name and that doesn't even allow for places whose names may be known bilingually in both English and Welsh.
The town in Wales that has the most letters is Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch, with 51 letters in its name.
