The Old Castle of the Counts of Celje

A castle built to watch the roads

Its oldest foundations go back to the later 1100s. From its height the fortress watched every route into Celje, and the town’s tourist office calls it the largest medieval castle in Slovenia. Its first owners were the Counts of Heunburg, from Carinthia. In 1333, after long inheritance disputes, it passed to the Lords of Sanneck, who took the castle’s name and began the story of Slovenia’s great dynasty.

The Counts of Celje

The Counts of Celje turned a cold fortress into a more comfortable home, with a new residential block whose two upper floors were even heated. They added the four-storey Frederick’s Tower, two turrets, battlements and a wooden rampart you can still walk today. Later, in the 1400s, at the peak of their power, they built a huge pentagonal tower, deepened the moat and added a drawbridge.

After Ulrich II, the last count, died in 1456, the walls were adapted for firearms, with gun loops and niches for heavy guns. Under an inheritance agreement signed earlier, everything passed to the Habsburgs and the castle slowly declined. I like walking up with that in mind, thinking how quickly a family went from more than 120 castles to nothing.

What to see at Celje Castle today

You can explore the courtyard, the walls and the rampart, with views over the Savinja and the town. In the warmer months re-enactment groups from across Slovenia arrive every weekend dressed as knights and court ladies, and in summer the courtyard hosts concerts, weddings and a medieval weekend. For a break there’s Café Veronika, right in the courtyard.

Bear in mind that Frederick’s Tower is closed for works until further notice, probably until November 2026, and so is the Theatre of Horror exhibition inside it.

Legends: Veronika of Desenice

The castle lives on its stories. None is told more often than the forbidden love between Frederick II and Veronika of Desenice. He married her in secret against the wishes of his father, Herman II, who locked him in the tower to starve. Veronika was acquitted in Slovenia’s first witchcraft trial and was drowned all the same. Legend has it that a loyal squire dug a tunnel to bring Frederick food.

Another tells how Ulrich’s lady saw a black crow before his last battle and begged him not to go. He went, saw the same crow in Belgrade and was struck down at that very moment. People said his ghost later appeared in the castle well, which is why it was bricked up.

Getting up and when to go

The access road has been under reconstruction since May 2026, so I’d do what Visit Celje suggests and go up on foot along the castle trails, by bike or on the Celebus town bus. In summer it stays open until 21:00, and the evening light over the valley is worth waiting for. Afterwards, head down to the old town for the Regional Museum, with Roman Celeia and the counts’ exhibition. If you’re touring Savinjska, the castle is one of its highlights and among the most storied castles in Slovenia. With time to spare, Šentjur, to the south-east, has the late antique site of Rifnik, and 16 km north lies Dobrna, with thermal water in use since 1403.
