Be aware of individuals collecting money for profit, and not the Church. More below.
Some of the reviews for St. Martin Church in Colmar, France are focused on impolite guests being told to remove their hats, or being denied entry with dogs. I would suggest to those entitled visitors to research what is, and is not proper to wear or do before you enter ANY place of worship. A Church is not there to entertain you, so if you cannot conform with simple rules of modesty in dress and behavior, do not enter.
Having said that, I would encourage visitors to be mindful of where/who receives your offering or donation. While entering St. Martin is free of charge, donations are accepted INSIDE the Church. Please be advised that an individual remains by the doors--he switches it often-- with a basket that resembles exactly the ones you would see during a Sunday Mass collection. This individual was confronted by some visitors and asked if he worked for the Church. He said that he does not. Upon that, he was told not to be collecting money, making visitors believe he was a Church employee. At the same time, a lady inside the Church who was cleaning, was made aware of the situation. It seems as if both people are in on it, and split the donations received, because she was clearly on the side of the scammer. Visitors solely intent for donations to go to the Church, and not for individual profit. This should be over sought by designated Church employees.
The Church is absolutely beautiful, and worth visiting, but please remember to be respectful in a place of worship, and be aware that scams are run most likely than not, in popular tourist destinations.
