Leibnitz (Salzburg)

On the hill above the Sulm and the Mur stands the archbishop's castle of Leibnitz, from which Salzburg colonised southern Styria; beside it the burgraves' castle of Polheim, held by Salzburg ministerials, and below it the market.

The lower castle will go to the new bishops of Seckau after 1218, and the two parts will quarrel across a dividing wall.
