The Basilica Cistern
The Basilica Cistern, also known as the Yerebatan Sarnıcı, is a remarkable underground structure located in Istanbul, Turkey. Constructed during the Byzantine period in the 6th century, it was designed to provide water to the city during times of drought and siege. The cistern’s most striking feature is its forest of columns, with over 300 marble columns supporting the ceiling, creating a mesmerizing visual spectacle.Among these columns, two are particularly notable for their decorative carvings, one featuring the head of Medusa. The cistern’s cavernous expanse and eerie atmosphere evoke a sense of mystery and intrigue, drawing visitors into its depths to explore its history and architectural ingenuity. Today, the Basilica Cistern stands as a testament to the engineering prowess of the Byzantine Empire and remains a popular tourist attraction, offering a glimpse into Istanbul’s rich past beneath the surface of modern life.
