Babelsberg Palace lies in the eponymous park and quarter of Potsdam, the capital of the German state of Brandenburg. For over 50 years it was the summer residence of Prince William, later Emperor William I and his wife, Augusta of the House of Saxe-Weimar. On 22 September 1862 in the palace and adjoining park the discussion between King William I and Bismarck took place that ended with the nomination of Bismarck as Minister President and Foreign Minister of Prussia. The building, designed in the English Gothic style, was built in two phases over the period 1835–1849. The contract to plan the palace was given to the architects Karl Friedrich Schinkel, Ludwig Persius and Johann Heinrich Strack.
Babelsberg Palace is managed by the Berlin-Brandenburg Foundation for Prussian Palaces and Gardens (Stiftung Preußische Schlösser und Gärten Berlin-Brandenburg) and is protected by UNESCO as a world heritage site within the Potsdam ensemble. The architecture of Babelsberg Palace formed the template for the construction of Kittendorf Palace between 1848 and 1853 in Mecklenburg-Vorpommern, by Schinkel's pupil, Friedrich Hitzig.
Since 2013, the Palace is undergoing an intense renovation of its facades and interiors.
References:Trenčín Castle is relatively large renovated castle, towering on a steep limestone cliff directly above the city of Trenčín. It is a dominant feature not only of Trenčín, but also of the entire Považie region. The castle is a national monument.
History of the castle cliff dates back to the Roman Empire, what is proved by the inscription on the castle cliff proclaiming the victory of Roman legion against Germans in the year 179.
Today’s castle was probably built on the hill-fort. The first proven building on the hill was the Great Moravian rotunda from the 9th century and later there was a stone residential tower, which served to protect the Kingdom of Hungary and the western border. In the late 13th century the castle became a property of Palatine Matúš Csák, who became Mr. of Váh and Tatras.
Matúš Csák of Trenčín built a tower, still known as Matthew’s, which is a dominant determinant of the whole building.
