History of Basilica Cistern

The basilica cistern Istanbul is believed to have been built in 532 AD by Justinian I, the Byzantine emperor. Measuring approximately 453 by 212 feet, the basilica cistern architecture boasts of a traditional Byzantine style. It can store almost 80,000 cubic metres of water at a time to supply water to the palace as well as the entire city of Byzantium. At the time when it was constructed, the basilica cistern Istanbul was located under the Stoa Basilica, which also gives it the name of “Basilica.”

In the year 476 AD, the Basilica Cistern was reconstructed by Illus, after parts of it were damaged by fire. Back then, it was decided that the basilica would consist of gardens, and would be surrounded by a colonnade, whilst also facing the Hagia Sophia. In the erstwhile eras, the basilica cistern Istanbul served as a water reservoir, and provided water for the Great Palace of Constantinople, and other buildings located on the First Hill. It also provided water for the Topkapi Palace during the Ottoman eras and has continued into the modern times as well.

Throughout history, the basilica cistern Istanbul has undergone a lot of repair, during the 18th century as well as multiple times in the 19th century by Sultan Abdulhamid II. The present-day Cistern was built by Constantine, and had fallen into disguise during the reign of the Ottoman. However, it was many years later, when scholar Petrus Gyllius found the monument, that the Cistern gained its lost fame back. As of today, it boasts of many raised wooden platforms, along with vaulted ceilings and a myriad of attractions, all of which make the basilica cistern Istanbul one of the most popular tourist attractions in the city.

Head of Medusa

Head of Medusa

One of the best attractions in the basilica cistern Istanbul are the two Heads of Medusa. When you walk to the back of the Basilica Cistern, you can witness two huge columns, both of which are held up by majestic Heads of Medusa. While one of the heads lays upside down, the other lies on its side, thereby giving the entire place an almost eerie, yet a thrilling appeal.

While it is not sure as to why the Heads of Medusa are placed in such positions here, it is believed that they were both recycled from an antique building during the late Roman period. According to legend, Medusa was a sea nymph, and was considered to be the most beautiful of the three gorgon sisters. She was also courted by Poseidon, and also made love to him in the temple of Athena. Due to this, Athena, out of sheer fury, transformed Medusa into a grotesque-looking beast, with snakes in place of hair. It is also said that anyone who would look into Medusa’s monstrous face, would turn into stone.

A lot of visitors and historians believe that the Heads of Medusa are placed in the basilica cistern Istanbul to ward off evil. Some others believe that it was the Emperor’s way of suggesting to his people that he considered the Pagan gods dead.
