The immaculately-looking white neoclassical palace on the Spreeweg, just off the Tiergarten’s northwestern corner is the official residence of the German President. The palace was erected in 1786 as a private residence for Friedrich the Great’s youngest brother Prince Ferdinand of Prussia as three-winged palace ideally situated on the Tiergarten hunting grounds. It was designed by architect Philipp Daniel Boumann. Over the centuries it became a school under Kaiser Wilhelm II (1888 – 1918) – the last German Kaiser – and a Reich guesthouse in 1939. The round arched windows of the side wings were converted from the original side entrances. The present building is the 1959 reconstructed version and only one room the Oval Saal (Oval Office) from Carl Gotthard Langhans is original. The President’s offices are located in the new building, the Bundespräsidialamt, south of the Palace, a contrasting glass and black granite edifice under heavy guard.References:
Narikala is an ancient fortress overlooking Tbilisi, the capital of Georgia, and the Kura River. The fortress consists of two walled sections on a steep hill between the sulphur baths and the botanical gardens of Tbilisi. On the lower court there is the recently restored St Nicholas church. Newly built in 1996–1997, it replaces the original 13th-century church that was destroyed in a fire. The new church is of 'prescribed cross' type, having doors on three sides. The internal part of the church is decorated with the frescos showing scenes both from the Bible and history of Georgia.
The fortress was established in the 4th century and it was a Persian citadel. It was considerably expanded by the Umayyads in the 7th century and later, by king David the Builder (1089–1125). Most of extant fortifications date from the 16th and 17th centuries. In 1827, parts of the fortress were damaged by an earthquake and demolished.
