About this place

The Basilica Cistern, also known as the Yerebatan Sarayı or the Sunken Palace, is an ancient underground cistern located in the Sultanahmet neighborhood of Istanbul, Turkey. Built during the Byzantine period in the 6th century, it served as a water storage system for the city.

The cistern is an architectural marvel, covering an area of approximately 9,800 square meters (105,000 square feet). It is supported by 336 columns, most of which are recycled from earlier Roman structures. The columns are arranged in 12 rows and create a mesmerizing forest-like atmosphere within the cistern.

One of the most remarkable features of the Basilica Cistern is its captivating lighting. The soft and dim lighting enhances the mystique of the underground space, creating a serene and almost otherworldly ambiance.

Visitors can walk along the raised wooden platforms that lead through the cistern, allowing them to explore its intricate architecture and marvel at the reflections of the columns in the water. Among the notable features of the cistern are the two Medusa heads, which are placed sideways and upside down at the base of two columns.

Today, the Basilica Cistern stands as one of Istanbul's most popular tourist attractions, attracting visitors from around the world. Its historical significance, stunning architecture, and atmospheric setting make it a must-visit site for those exploring the rich cultural heritage of Istanbul.
