This one you have to drive down Soi Chayapuk 2, take the turn off and head into the jungle, 500 meters up a dirt track and your there.
I think the cross at the top is made from stainless steel, hell at least the place has some nice stained glass, although I did wonder about the chain and padlock on the door, had somebody locked the people in there and were getting ready to burn it down? or had they suffered too many thefts?
