The mansion was built in the second half of the 17th century to replace the deteriorating and inaccessible fort that stood on the steep hill named Kozlov Rob in the middle of the valley since the 12th century.

The governor Peter Anton Coronini commissioned it. Having remained in the family for almost 200 years, Luigi Silverij Kremer bought the large estate in 1848 and soon sold it off to farmers, piece by piece.

The last private owners Janez Permerstein and Filippo Persoglia bought the humble remains of the land and the Mansion in 1871.

At its grandest the building comprised the Mansion tract, four corner towers, two lower buildings for subsidiary functions and the Anton Padovanski Chapel. A lawn stretched across the frontal court, separated from the main road by a stone wall, across which the path lead to the main doors.

The Mansion Park, planted with diverse plants and crisscrossed with footpaths, lay on the southwestern edge of the terrace; a gazebo decorated the park's boundary.

The only surviving tree in the park, now no longer surrounded by other trees, but by cars and buildings, is an enormous tulip poplar

The building was refurbished several times since its beginnings.

The last major adaptations were carried out during WWI, when it suffered severe damage.

Renovation works were initiated in 1992, and the house is now completely renewed from basement to attic.
