Galleries in the Barmsteine were used by the nearby brewery, Hofbräu Kaltenhausen, to store beer.

Even during the Nazi era the Barmsteine were visibly and invisibly used: in addition to the use of the hidden galleries as a site for the armaments industry, a large, white swastika was painted on the rocks so that it could be easily from the direction of Austria; this was even before the Anschluss of Austria to Germany.
After the war it was removed and is no longer really visible today.
