The town of Bergen developed around a chapel and is mentioned as far back as the tenth century as well. An old local legend is the "Miracle of Bergen", which is said to have occurred during the St. Elisabeth's Flood of 1421. The story goes that the "schout" (sheriff) of Bergen found a chest containing hosts (the thin wafers used in Holy Communion) from the church of Petten which had floated to Bergen during the flood. The seawater that penetrated the chest had turned into blood. There is also a second miracle story, thought to have occurred in 1422, whereby hosts turned into blood. On the site where the miracle of Bergen is said to have happened, a chapel was erected. Bergen became a place of pilgrimage, and Roman-Catholic processions were held at the site for centuries and are still ongoing today.
