 The High Court on the Heath – a geographical area as well as an actual court – was the land between the Steinalb, the Glan and the Nahe, which in the late 10th century became more heavily settled, as witnessed in documents from both Emperor Otto III and Archbishop Willigis of Mainz.It is likely that the area later passed to the Electorate of the Palatinate as an Imperial pledge, and was then transferred by that state to the Waldgraves and Rhinegraves of Steinkallenfels and Grumbach, along with the high court jurisdiction.Already by Ottonian times, the area was no longer held by the kingly treasury anyway.
