Grumbach (Rothenfels)

Rothenfels is a rock castle over the Main in the Spessart bend, held by the Grumbach lords as a fief of Würzburg.

It watches the river between the counts of Rieneck upstream at Gemünden and the counts of Wertheim downstream, and it will pass to the Rieneck by marriage in 1243.

NDB, Rieneck: in 1243 Ludwig II of Rieneck married Adelheid of Grumbach, heiress of the Grumbach dynasts, and gained the Würzburg fief of Rothenfels, after which his line was often named. That the castle was built about 1148 by Marquard of Grumbach, Frederick I's procurator in Italy, is the usual account of its foundation and is not checked here.
