You should visit Augsburg and it's region. Something for everybody's taste is offered. Whether you want to join festivities (ask for dates), do some sightseeing or join on a cultural trip - you will not be disappointed.

Many churches display nativity scenes. This was done to fight the reformation. Many families even had them in their houses. People visited each other around Christmas to compare them. I observed similar behavior in Canada with Christmas lights. They are even having contests.

In certain areas "Fasting Sunday" (catholic) is still celebrated with fires. Occasionally a Judas made out of straw is burned.
