Today, the lowland castle probably built in 1185 presents itself to the visitor as a fort-type, compact castle complex. It formerly served to safeguard the ferry to Bingen and later as a Ganerbenburg. For hundreds of year, the legend of the knight, Ritter Hans Brömser, who was captured by the Saracens after a successful crusade and thrown into the dungeon, has been in circulation. While imprisoned, he is said to have made a vow to build a chapel next to his castle - the selfsame Brömserburg Castle. Subsequently, he is said to have found a file with which he was able to loosen his chains. The Castle houses the Rheingau Wine Museum today.
