Beautiful Army headquarters from across the world

Indian Army will have a new headquarters in the next five years. Defence Minister Rajnath Singh laid the foundation stone of the Army headquarters' new building in Delhi Cantonment last week. Christened 'Thal Sena Bhawan', the multi-storeyed complex is designed "like a rising sun" and it will be spread over nearly 39 acres. Here are some of the other beautiful Army headquarters from across the world:

Majestic Buenavista palace in Spanish capital Madrid houses the headquarters of the Spanish army. Built in 1767, it used to be the residence of the Dukes of Alba. Closely associated with the Army since 1816, the palace was first opened as a Military Museum. The palace became the seat of the Ministry of War in 1847, the Ministry of Army in 1939 and later the Ministry of Defense from 1977 to the 1981.

Inaugurated in 2015, the building is dubbed as the "French Pentagon". The hexagon shape of the building is also based on the visual symbol of France’s hexagonal-shaped geography, which long ago earned it the nickname the Hexagon (“L’Hexagone”). The hexa shaped building houses more than 9,000 personnel from the French Army, French Navy, and French Air Force. The seven-story control-and-command center is built on 41 acres around a former army air base. The walls of the seven-story command and control center can withstand even a missile strike. The complex includes three day care centers, the largest solar-paneled roof in Paris, a gym, a hair salon, 12 gardens, two cafeterias, an auditorium, and a $32 million pool.

The picturesque ministry of defence building houses the Russian Army headquarters in Moscow. The building was designed by Russian architect Lev Rudnev and was renovated by Mikhail Posokhin who was the main architect of Moscow (1960–1982). Ground was broken for construction in 1940, and the building was dedicated in 1952. The building was also renovated in the 1980s. The walls of eight-floors buildings are decorated with marble, ural stones -- serpentine and granite.

Five-sided building in Virginia, Pentagon, serves as the headquarters of the US armed forces. The Pentagon is the world's largest office building, with about 6,5 million sq ft of space. It has five sides, five floors above ground, two basements, and five ring corridors per floor. The central five-acre pentagonal plaza is nicknamed "ground zero" on the presumption that it would be a prime target in a nuclear war. Because of its innovative construction, it is possible to walk between any two points within the building in approximately seven minutes.
