 The best known Landvogt of Lenzburg was Adrian I of Bubenberg, from 1457 to 1461, later Schultheiß of Bern and hero of the Battle of Morat.In 1509–10, extensive work was carried out at the castle, including partial demolition and rebuilding of the unfinished Knights' Hall.In 1518 there was a serious fire; which buildings were destroyed is not recorded (most likely the "Arburghaus" on the north side).
