Manor Sixta in Jakovlje is an example of the historical heritage from Hrvatsko zagorje with an interesting past and an exciting future. The thesis concentrates on the manor and estate that was owned by many influential families throughout history, among which it is important to single out the Oršić and Josipović families, but also the Sixta family that took care of the estate during the first half of the 20th century. The rich history of ownership greatly influenced the formation of the manor as we know it today. It was built in three phases during the 18th and 19th century. The first and second construction phases are closely related and follow the development of the building from the unfinished baroque manor house built by Mathias Leonhart in the 1750s to the extension of the side wings and the completion of the manor at the end of the 18th century. The third construction phase includes the restoration of the manor in a historicist manner with recognizable elements of architectural plastic from the end of the 19th century. Historicist interventions are visible on the facade, but also in the interior. In addition to important information about the owners and the architecture of the building, this thesis also contains information about the conservation and restoration procedures that were undertaken and touches on the topic of revitalization of the whole in Jakovlje, whether it is about the building itself or about the park within which the International Sculpture Park (Međunarodni park skulptura) is located. All these valuable details marked and continue to mark Manor Sixta in Jakovlje, which through recent renovation projects is entering its most active phase.
