Nürnberger Burg
In 1105 Nuremberg Castle and the city of Nuremberg were partially destroyed during the conflict between Emperor Henry IV and his son Henry V. In order to better protect the castle and the city in the future, Henry IV appointed the brothers Gottfried II and Conrad I of Raabs as burgmann of Nuremberg castle, with the title official of "Castellan". Thus, they became the first Burgraves of Nurembert. Gottfried's son Gottfried III was the first member of the family to be called "burggravius of Norimburg" in an official document.
