Göreme Open-Air Museum, a UNESCO World Heritage Site, is one of Cappadocia’s most significant cultural and religious landmarks. Dating back to the 10th–12th centuries, this monastic complex features rock-hewn churches, chapels, and monasteries decorated with well-preserved Byzantine frescoes depicting biblical scenes. Highlights include the Dark Church, Apple Church, and St. Barbara Chapel. The site offers a unique insight into early Christian monastic life, art, and architecture, set against Cappadocia’s surreal rock formations.
