Kayseri Castle is a majestic historical structure located in the heart of the city of Kayseri, Turkey. This citadel is one of the best-preserved in the country and serves as a striking example of medieval military architecture. Built from durable and somber gray-black volcanic stone, it served as the city's primary defensive bastion for centuries.
The architectural ensemble consists of two parts: the outer and inner fortress, also known as the citadel. Massive walls, reaching a thickness of three meters, and nineteen watchtowers made the fortress nearly impregnable. You can enter the grounds through two main gates, each with its own rich history.
