Originally built as the Church of the Holy Saviour in Chora, it dates back to the 4th century and was rebuilt in its current form in the 14th century. Over the centuries, it has served as a church, a mosque, a museum, and once again a mosque since 2020. Despite these changes, it remains a must-visit destination for history and art lovers, offering a glimpse into one of the best-preserved examples of Byzantine religious art. One of the most breathtaking artworks inside Kariye Mosque is the Anastasis (Resurrection) fresco, which portrays Christ pulling Adam and Eve from their tombs, symbolizing victory over death and the promise of salvation. This fresco is considered one of the most important depictions of the Last Judgment in Christian art. The walls and ceilings are also covered with intricate mosaics, telling the stories of the life of Christ and the Virgin Mary in extraordinary detail. Even though it now functions as a mosque, visitors can still admire its rich history and artistic beauty. With its ornate domes, elegant stonework, and breathtaking frescoes, Kariye Mosque offers a unique journey into Istanbul’s past, making it a hidden treasure for travelers looking to explore the city's diverse cultural heritage.
