The Royal Palace of Madrid (Palacio Real de Madrid) is the official residence of the Spanish Royal Family at the city of Madrid, but it is only used for state ceremonies. Several rooms in the palace are regularly open to the public except during state functions.
The palace is located on the site of a 9th-century Alcázar (Muslim-era fortress), near the town of Magerit, constructed as an outpost by Muhammad I of Córdoba and inherited after 1036 by the independent Moorish Taifa of Toledo. After Madrid fell to King Alfonso VI of Castile in 1083, the edifice was only rarely used by the kings of Castile. In 1329, King Alfonso XI of Castile convened the cortes of Madrid for the first time. King Felipe II moved his court to Madrid in 1561.
The old Alcázar was built on the location in the 16th century. After it burned 24 December 1734, King Felipe V ordered a new palace built on the same site. Construction spanned the years 1738 to 1755 and followed a Berniniesque design by Filippo Juvarra and Giovanni Battista Sacchetti in cooperation with Ventura Rodríguez, Francesco Sabatini, and Martín Sarmiento. King Carlos III first occupied the new palace in 1764.
The last monarch who lived continuously in the palace was King Alfonso XIII, although Manuel Azaña, president of the Second Republic, also inhabited it, making him the last head of state to do so.
The palace has 135,000 square metres of floor space and contains 3,418 rooms. It is the largest royal palace in Europe by floor area. The interior of the palace is notable for its wealth of art and the use of many types of fine materials in the construction and the decoration of its rooms. These include paintings by artists such as Caravaggio, Francisco de Goya, and Velázquez, and frescoes by Giovanni Battista Tiepolo, Juan de Flandes, Corrado Giaquinto, and Anton Raphael Mengs. Other collections of great historical and artistic importance preserved in the building include the Royal Armoury of Madrid, porcelain, watches, furniture, silverware, and the world's only complete Stradivarius string quintet.
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.
