It was built in gothic style but full of non-catholic symbol. You will see some strange or even, some may say, heresy symbols.
The good thing was that after the movie, lots of visitors came to this chapel. The chapel was lack of funding to repair its roof years ago but now they can do the repair work by charging the visitor entrance fee. Now they can even have enough funding to run the chapel. I do concur with some academic that no one, either public or Christians, wants to dig up the secret of this chapel as this will be a loss-loss situation.
