Rostov Kremlin is located in the very centre of the city. It was built in the 17th century. Though the strong fortified walls and 11 towers were really more for decorative purposes rather than defensive ones, the new residence nevertheless started to be referred to as a kremlin (fortress). Now, it is the Rostov Kremlin State Museum. Inside the Kremlin is separated into three parts: Cathedral Square, the central part and the Metropolitan's Gardens. The Kremlin's main cathedral is the Dormition Cathedral of the 16th century. A ticket must be bought to enter its territory and individual tickets must be bought to visit each of its permanent exhibitions devoted to Rostov enames, bells, icons, etc.
