A long historiographic tradition places the second Bayernburg at or near Raudonė, but it lacks proof as archaeological research dates Raudonė only to the 16th century. Chronicler Wigand of Marburg mentioned that the second Bayernburg was located about one mile west of the first, but a mile is an ill-defined measure of distance that varied greatly over the ages and medieval period is known for its inaccurate measurements. According to Zabiela, the nearest hillfort that could have housed the second Bayernburg is Maštaičiai (Narkūnai) hillfort located about from Plokščiai hillfort ().
