Old City is often called a city in the city. When you set foot in the castle directly, it is like if you are falling into another world – to the medieval city. Modernity and past are separate from the fortress walls. The Old City is surrounded by fortress walls with a height of 8-10 meters wide and 3.5 meters wide. An ancient city with an area of 22 hectares is an example of a city-style culture.The Maiden Tower and the Shirvanshahs Palace (XIII-XVI centuries) were included in the UNESCO World Cultural Heritage list in 2000.
