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:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
