The people in Fatima are trustworthy and sometime go out of their way to help. It's the unknown traveller that may be next to you in the Bus or Terminal that you have to become aware of. In Fatima itself, I have always felt safe in knowing that my things in my room are safe. I have been ther many time and have yet to have bad vibes. Lisbon and bigger Cities are different. But as a precaution always have your wallet in your front pocket and ladies, leave your purse and/or valuables in your room or the Hotel Safe. Don't carry your Passport from the Hotel !!!
before entering the sanctuary precynt you'll see this sign with the rules of conduct: don't shout, don't wear skimpy clothes, don't play musical instruments, don't rude your bicycle, don't use your mobile phone, don't play football, don't listen to the radio, don't smoke, don't beg for money.. and, well - pay attention to pickpockets and to your car-keys. In other words: nothing is really safe here, too.
Bythe way... nothing says that you can't (or can, for that matter) take photographs.
If you want some spiritual peace try to avoid the most important dates such as May 13 or October 13 'coze in such dates there are thousands and thousands of pilgrims.
When you enter Fatima you are not allowed to smoke. This rule applies when you cross the yellow pillars. You can see them on the picture.
Please remember that this is a place of worship and that there are many people making a pilgrimage to the site for religious reasons.
RESPECT their religious beliefs!
