El Teatro Romano is the oldest survived monument in Málaga City; it is situated at the foot of the famous Alcazaba fortress. The theatre was built in the first century BC, under Emperor Augustus, and was used until the third century AD. Subsequently it was left to ruin for centuries, until the Moors settled in Andalucía. In 756-780AD the amphitheatre was used as a quarry by the Moorish settlers , to excavate the stone used to build the Alcazaba fortress - you can see some Roman columns and capitals in the fortress. Over time it became buried under dirt and rubble, and remained hidden there for almost five centuries.
The theatre was rediscovered in 1951, when the construction of Casa de Cultura uncovered the first archaeological clues. The construction of the gardens was abandoned, and instead excavations began. In 1995 a polemic decision was made to demolish the Casa de la Cultura, which stood over a third of the site. Once the site had been fully excavated, a large scale restoration project began, which proved more difficult than anticipated, as many of the missing pieces are now part of the foundations of the neighbouring Alcazaba.
On 15 September 2011, 27 years after reconstruction began, El Teatro Romano reopened to the public, and held its first stage performances for millenia, with performances from Andrés Mérida, Daniel Casares, and Carlos Álvarez, reading from Juvenal Soto and the poetry of Pablo Picasso and Manuel Alcántara. The amphitheatre is now open throughout the year for visitors, and in summer, it will be used for open-air performances. It seats 220 spectators.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
