THE CITY WITH THE LONGEST NAME

Some tourist was in my office today to make flight reservation to a city Llanfair PG as abbreviated. Kind of look out on my computers with no answers until i finally searched it on Google. The name is  Llanfair­pwllgwyn­gyllgo­gerychwyrn­drobwll­llanty­silio­gogogoch 
It has 58 letters all together.
which in English means "Saint Mary's Church in the hollow of white hazel near a rapid whirlpool and the Church of Saint Tysilio near the red cave".
The locals call it Llanfairpwll (pronounced thlan vire puth).
This city is a town in North Wales.
But still i need someone to pronounce this for me, before you look up Bangkok true name in Thailand for me..
