Friesach has four medieval fortress ruins ranged along the hills rising above Hauptplatz to the west, all offering excellent views. The northernmost is Burg Geyersberg ; the furthest south are the Virgilienberg ruins. The middle two (Rotturm and Petersberg ) are the most easily visited from the centre. There are lovely views from Peterskirche , accessible by paths ascending from the front of the Gothic Stadtpfarrkirche , with Romanesque elements dating from AD 927.
All fortresses are connected by the Burgwanderweg that winds through the bucolic landscape with views over town.
