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:
Derbent is the southernmost city in Russia, occupying the narrow gateway between the Caspian Sea and the Caucasus Mountains connecting the Eurasian steppes to the north and the Iranian Plateau to the south. Derbent claims to be the oldest city in Russia with historical documentation dating to the 8th century BCE. Due to its strategic location, over the course of history, the city changed ownership many times, particularly among the Persian, Arab, Mongol, Timurid, Shirvan and Iranian kingdoms.
Derbent has archaeological structures over 5,000 years old. As a result of this geographic peculiarity, the city developed between two walls, stretching from the mountains to the sea. These fortifications were continuously employed for a millennium and a half, longer than any other extant fortress in the world.
A traditionally and historically Iranian city, the first intensive settlement in the Derbent area dates from the 8th century BC. The site was intermittently controlled by the Persian monarchs, starting from the 6th century BC. Until the 4th century AD, it was part of Caucasian Albania which was a satrap of the Achaemenid Persian Empire. In the 5th century Derbent functioned as a border fortress and the seat of Sassanid Persians. Because of its strategic position on the northern branch of the Silk Route, the fortress was contested by the Khazars in the course of the Khazar-Arab Wars. In 654, Derbent was captured by the Arabs.
The Sassanid fortress does not exist any more, as the famous Derbent fortress as it stands today was built from the 12th century onward. Derbent became a strong military outpost and harbour of the Sassanid empire. During the 5th and 6th centuries, Derbent also became an important center for spreading the Christian faith in the Caucasus.
The site continued to be of great strategic importance until the 19th century. Today the fortifications consist of two parallel defence walls and Naryn-Kala Citadel. The walls are 3.6km long, stretching from the sea up to the mountains. They were built from stone and had 73 defence towers. 9 out of the 14 original gates remain.
In Naryn-Kala Citadel most of the old buildings, including a palace and a church, are now in ruins. It also holds baths and one of the oldest mosques in the former USSR.
In 2003, UNESCO included the old part of Derbent with traditional buildings in the World Heritage List.
