Istanbul Underwater Palace

The Istanbul Underwater Palace generally refers to the Basilica Cistern. Here's an introduction: - Overview: Located in Istanbul, near the Blue Mosque and Hagia Sophia. Built in 542 AD, it was a water reservoir constructed by Emperor Justinian I of the Byzantine era, using seven thousand slaves on the ruins of a church. It is 140 meters long, 70 meters wide, and features 336 nine-meter-high Corinthian columns supporting a massive brick vaulted ceiling. It has a water storage capacity of 100,000 tons. - Architectural Features - Columns: The columns were transported from temples in the Anatolian region. The capitals and bases of the columns have different patterns, showcasing diverse architectural styles and sculptural art. - Weeping Column: There is a "Weeping Column" in the cistern, decorated with tear-like patterns and with water flowing down from above. It is said to commemorate the slaves who died during the cistern's construction. - Medusa Heads: Two Medusa heads reside in the cistern, one inverted and the other sideways, adding a touch of mystery. The reason for their placement remains a puzzle. - Historical Changes: Served as an essential water storage facility during the Byzantine period, ensuring water supply for the palace and surrounding areas; abandoned during the Ottoman Empire; rediscovered by the Dutch in the mid-16th century and opened to the public in 1987. - Cultural Value: Witnesses the historical changes and cultural integration of Istanbul, representing a significant part of Byzantine culture and architectural art. Its unique landscape and mysterious atmosphere make it a popular filming location for movies and TV shows, such as "From Russia with Love," "The International," and "Inferno."
