I wish Duo didn't capitalize one word in the group. I realize that's correct in the answer but it's a big hint that I can't avoid.
There are many Newports in Wales. Trefdraeth in Pembrokshire is one example.
Trefdraeth is worth a visit if you like the sea and practising your Welsh. If you meet someone from the Trefdraeth area, you might hear them use the local pronunciation too: Tidreth.
Whereas the Newport called Casnewydd is a very bad place to practice your Welsh!
