The crown's rock above the Rhine between Andernach and Linz: a royal castle (Reichsburg) since 1002, with a toll station recorded in 1071, where Henry IV fetched the regalia in 1105 and where they were kept in 1125.
A family of burgraves held it for the king until about 1417; Charles IV handed its overlordship to Trier only in 1374. It stands on the stretch of the Rhine that both parties used in 1198-1199, between Cologne's towns of Andernach and Linz and Trier's Koblenz.
