Kačina is a significant empire style palace built in place of the defunct medieval village Kačín. It was built as a prestige mansion of the supreme burgrave of the Kingdom of Bohemia and president of governorate Jan Rudolf Chotek (1748–1824) from 1806 to 1824. The architectural scheme was drawn up by Saxon royal architect Christian Franz Schuricht (1753–1832) from Dresden. Johann Philipp Jöndl (1782–1870) and in the last few years also had controlled running the construction. He also eminently influenced the final appearance of the castle.
Functionally the castle is divided into three parts. The main building with exquisite halls and the residence of earl family, then two quarter circle adjacent lower wings with pillared colonnade where the guest rooms were situated. To those wings were connected other pavilions. In the right one is situated never finished mansion chapel and theatre which were finished in the first half of 19th century.
In the left one there is a Chotek's extensive library dated from 16th to 19th century. The castle is surrounded by vast park that was founded already in 1789 according to the plan of famous Viennese botanist Nikolaus Joseph von Jacquin (1727–1817), it was completed thirteen years earlier than the castle itself.References:
Sirmione castle was built near the end of the 12th century as part of a defensive network surrounding Verona. The castle was maintained and extended first as part of the Veronese protection against their rivals in Milan and later under the control of the Venetian inland empire. The massive fortress is totally surrounded by water and has an inner porch which houses a Roman and Medieval lapidary. From the drawbridge, a staircase leads to the walkways above the walls, providing a marvellous view of the harbour that once sheltered the Scaliger fleet. The doors were fitted with a variety of locking systems, including a drawbridge for horses, carriages and pedestrians, a metal grate and, more recently, double hinged doors. Venice conquered Sirmione in 1405, immediately adopting provisions to render the fortress even more secure, fortifying its outer walls and widening the harbour.
Thanks to its strategical geographical location as a border outpost, Sirmione became a crucial defence and control garrison for the ruling nobles, retaining this function until the 16th century, when its role was taken up by Peschiera del Garda.
