2. How Was The Basilica Cistern Found?

The cistern was left alone for a long time after the conquest of Istanbul. It was discovered by the Dutch traveler P. Gyllius who came to explore the Byzantine ruins in the mid-16th century. While walking around Hagia Sophia, P. Gyllius heard and observed that the people living here were getting water from the wells inside their homes and even fishing. He entered the cistern with a torch in his hand from the stone-lined courtyard of a wooden building on a large underground cistern. P. Gyllius traveled with a cistern under very difficult conditions and took his measurements and determined the columns. He announced all these determinations to the world by writing in his travel book. The Cistern was thus known.

3. History

This place was built by Emperor Justinian, who made Hagia Sophia either. One of the most important emperors of the time, First Justinian made the Byzantine Empire the most magnificent. He enriched the lands where the empire was located, making people more productive. Justinian, who built the Hagia Sophia, built the Basilica Cistern and provided the people living in the city to access the water. It is said that the water supply to the Basilica Cistern with aqueducts from the freshwater source, 19 km away from the city. The construction of the cistern took 38 years.

4. Architectural Structure

The cistern is a giant building covering a rectangular area of ​​140 meters in length and 70 meters in width. Covering a total area of ​​9,800 square meters, this cistern has a water storage capacity of approximately 100,000 tons. There are 336 columns, each 9 meters high, in this cistern, which is descended by a stone staircase with 52 steps. These columns, which are located 4.80 meters apart, form 12 rows, each containing 28 columns. Most of the columns, most of which were found to be collected from older structures and carved from various types of marble, consist of a single piece and some of them consist of two pieces. The titles of these columns have different features in places. While 98 of them reflect the Corint style, some of them reflect the Doric style. The vast majority of the columns in the cistern are cylindrical, except for a few of them in angular or grooved form. Since the 8 columns located in front of the northeastern wall towards the middle of the cistern were exposed to the risk of breaking during construction made in 1955-1960, each of them was enclosed in a thick concrete layer and thus they lost their former features. The ceiling space of the cistern was transferred to the columns by means of arches. The walls of the cistern, which are made of brick, 4.80 meters thick and the floor with brick floors, are plastered with a thick layer of Horasan mortar and made waterproof.

5. Medusa’s Head

In the northwest corner of the cistern, there are two Medusa heads under two columns. These two sculptures are one of the Roman masterpieces. Medusa heads used as a base under these columns are unknown where and how they were brought. According to legend, Medusa is one of three Gorgons, the female monster of the underworld in Greek mythology. Of these three sisters, Medusa, the head of a snake, has the power to turn those who care for her into stone. According to one view, Gorgona paintings and sculptures were used to protect large buildings and private places at that time, and that is why Medusa’s head was placed.
According to another rumor, Medusa was a girl who boasted with her black eyes, long hair and a beautiful body. Medusa loved Zeus’ son Perseus. Meanwhile, Athena liked Perseus and was jealous of Medusa. That’s why Athena turned Medusa’s hair into snakes. After that, everyone who caught the eye with Medussa turned to stone. Later, Perseus cut off Medusa’s head and took advantage of her power to defeat many enemies. Based on this, the Head of Medusa was engraved on the sword hilt in Byzantium and placed opposite to the column bases. The reason it is placed upside down is the fear of rumor.

6. Weeping Column (Tear Column)

There is a column in the underground palace, which immediately stands out among the others: Because there are tear-like shapes on this column, and the column “cries” like it never stops. More than 7000 slaves worked in the construction of the palace. Hundreds of slaves died. According to legend, this column was made for slaves who died. It is said that the crying sounds of these slaves were heard after the palace closed the visit. This is too mysterious! You can make a wish by throwing money in the water in front of this column.
