Kulmer Castle

Kulmer Castle (Kulmerovi dvori) is a historic estate in the Šestine neighborhood of Zagreb, set at the foot of Mount Sljeme on the Medvednica massif. The grounds cover roughly 55,000 square meters, making it one of the largest historic properties on the northern edge of the Croatian capital.

What is the story behind the castle?

The site's origins trace back to the late 16th century. After a devastating earthquake struck the region in 1590, Stjepko Gregorijanec, then owner of the Medvedgrad fortress, relocated to a newly built manor house in Šestine — the structure that eventually grew into today's estate. During the 17th century the property passed to the noble Zrinski family, and Count Petar Zrinski enlarged it in a late-Renaissance style, giving the building a far more imposing appearance.

Over the following decades ownership shifted several more times: the Turovicz, Mikulić and Čikulin families held the estate in turn, followed by the Sermage nobility. A defining moment came when Ivan Emil Kulmer acquired the property through his marriage to Judita, Countess Sermage. Wealthy and influential, Kulmer financed a major expansion and renovation of the residence — and it is his family name that the estate still carries today.

The 20th century was far less kind to the building. The last Kulmer family owner lost the property when it was expropriated under socialist Yugoslavia. Even before that, in 1894, the castle had been ransacked and partly stripped, and it burned down during the Second World War. Decades of neglect followed until 1999, when Croatian entrepreneur Ivica Todorić bought the land together with the ruined castle.

What will you see on site?

The estate layers several architectural periods on top of one another — from the original manor house built after the 1590 earthquake, through the late-Renaissance additions made under the Zrinski family, to the 19th-century remodeling carried out during the Kulmer era. The sprawling park surrounding the building extends naturally up the slope of Sljeme, and the grounds open onto views over Zagreb and the wooded ridge of Medvednica.

Since the property has been privately owned since 1999, visits are largely limited to viewing the castle from outside — from the streets and walking paths of Šestine, which offer the best vantage points onto the building against its forested backdrop.

How do you get there?

Šestine sits in the northern part of Zagreb, right at the gateway to Medvednica and the popular route up to Sljeme. It's a leafy, villa-lined neighborhood that locals often use as a starting point for hikes and mountain excursions, so a stop by the castle pairs naturally with a trip toward the summit.

When is the best time to visit?

Spring and autumn are the most rewarding seasons for a walk around the castle grounds, when the park and the slopes of Sljeme are at their greenest and temperatures are comfortable for longer strolls. Combining the visit with a hike up Medvednica makes sense, since the area around the castle serves as a natural starting point for trails heading further up the mountain.
