In 1173, the son of Hermann von Stein, Count Gebhart, named himself after the Hohenegg Castle.

After 1188, the castle came into the possession of a branch of the Counts of Hohenburg, who brought it into their marriage with Diepold III, Margrave of Vohburg.

In 1464, Wolfgang V of Walsee sold Hohenegg Castle to Matthäus Spaur, who had made the extensions a year earlier.

Raimondo Montecuccoli later had Hohenegg expanded again and also built the outer bailey and the seven-story bell tower.

During World War II, a resistance group from the Markersdorf air base used the lonely area to establish a secret meeting place and camp.
