If you visit to a new country that speaks a different language, you are bound to mispronounce words and places. No biggie, faux pas of travelers from foreign lands.
English seems easy, but it is an interesting and tricky language on its own! UK English, especially, is a whole other level. If you want to go the extra mile though and impress both locals and tourists, it would pay to do a little bit of research on how to properly pronounce places.
