Tivoli Castle is a mansion located in the Ljubljana's Tivoli Park. In the early 15th century, a tower stood in the woods above the site; it was owned by Georg Apfalterer, an ally of Duke Frederick (later Holy Roman Emperor Frederick III). The tower was destroyed by Frederick II, Count of Celje in 1440.
The current structure was built in the 17th century atop the ruins of a previous Renaissance-period castle, the mansion was initially owned by the Jesuits, but came into the possession of the Diocese of Ljubljana following the 1773 suppression of the Jesuit order. Used as the bishop's summer residence, it was surrounded with orchards.
In the mid-19th century, it was bought by the Austrian emperor Francis Joseph I, who in 1852 presented it as a gift to the veteran Habsburg marshal Joseph Radetzky. Radetzky renovated the mansion in the Neoclassical style, giving it its present appearance, and spent much of his retirement in it with his wife Francisca von Strassoldo Grafenberg, a local Carniolan noblewoman.
The field marshal Joseph Radetzky von Radetz (1766–1858) contributed a lot to the arrangement of Tivoli Park. There was a full-size cast iron statue of Radetzky on display in Ljubljana on the steps in front of Tivoli Castle from 1882 till 1918. In 1851, it won a prize at the Great Exhibition in London. Today, it is preserved by the City Museum of Ljubljana. The statue's pedestal, however, remains at its original place.
In 1863, the mansion was bought by the Municipality of Ljubljana, who used it as (among other things) a poorhouse, later subdividing it into condominiums. In 1967, it was again renovated and became the venue for the International Centre of Graphic Arts.
In 1864, the Austrian sculptor Anton Dominik Fernkorn created four cast iron dogs, still on display in Tivoli Park in front of Tivoli Castle. The dogs do not have tongues, and it has been falsely rumoured that Fernkorn committed suicide by shooting himself due to this mistake.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
