The Torre del Oro ('Tower of Gold') is a dodecagonal military watchtower erected by the Almohad Caliphate in order to control access to Seville via the Guadalquivir river.
Constructed in the first third of the 13th century, the tower served as a prison during the Middle Ages. Its name comes from the golden shine it projected on the river, due to its building materials (a mixture of mortar, lime and pressed hay).
The tower is divided into three levels, the first level, dodecagonal, was built in 1220 by order of the Almohad governor of Seville, Abù l-Ulà; As for the second level, of only 8 meters, also dodecagonal, was built by Peter of Castile in the fourteenth century, a hypothesis that has been confirmed by archaeological studies; The third and uppermost being circular in shape was added after the previous third level, Almohad, was damaged by the 1755 Lisbon earthquake. Rebuilding of the third level was made by Brusselian military engineer Sebastian Van der Borcht in 1760.
The Torre de la Plata, an octagonal tower, is located nearby, and is believed to have been constructed during the same era.
The tower was badly damaged by the Lisbon earthquake of 1755, and the Marquis of Monte Real proposed demolishing it to widen the way for horse-drawn coaches and straighten access to the bridge of Triana; however, the people of Seville objected and appealed to the king, who intervened. In 1760, the damage was repaired, with repairs to the bottom floor of the tower, reinforcement with rubble and mortar, and the creation of a new main access via the passageway to the path around the wall. That same year, the upper cylindrical body was built, a work of the military engineer Sebastian Van der Borcht, also architect of the Royal Tobacco Factory of Seville. These works changed the appearance of the tower as compared to what is seen in engravings from the sixteenth or seventeenth centuries.
The Revolution of 1868 brought another crisis to the tower as revolutionaries demolished the decorative facing of the walls and put it up for sale. Opposition from the citizens of Seville kept the tower from being destroyed, and in 1900 it was again restored, this time by engineer Carlos Halcón. On April 10, 1923, King Alfonso XIII visited the tower, and on March 21, 1936 the Maritime Museum was installed in the Tower by order of the Admiralty. In September 1942, more restoration work began. The appearance of the facade was improved, two floors were set up for museum display, and the third floor was prepared to house researchers. The museum held its grand opening on July 24, 1944, for which occasion 400 museum pieces were brought from the Naval Museum of Madrid.
On August 13, 1992, the Torre del Oro was made a brother to the Tower of Belem of Lisbon to celebrate the Universal Exposition in Seville. As of 2008 the museum displayed a variety of old navigational instruments and models, as well as historical documents, engravings, and nautical charts, relating Seville to the Guadalquivir River and the sea. The tower was again restored in 2005.References:
The Odeon of Herodes Atticus is a stone theatre structure located on the southwest slope of the Acropolis of Athens. It was built in 161 AD by the Athenian magnate Herodes Atticus in memory of his wife, Aspasia Annia Regilla. It was originally a steep-sloped theater with a three-story stone front wall and a wooden roof made of expensive cedar of Lebanon timber. It was used as a venue for music concerts with a capacity of 5,000. It lasted intact until it was destroyed and left in ruins by the Heruli in 267 AD.
The audience stands and the orchestra (stage) were restored using Pentelic marble in the 1950s. Since then it has been the main venue of the Athens Festival, which runs from May through October each year, featuring a variety of acclaimed Greek as well as International performances.
