Standing on the bank of the River Kazanka opposite to the Kremlin is a marriage registry office with a big difference as it takes the form of a giant cooking pot known as a kazan. According to legend Kazan gets its name from such a cooking utensil after a servant dropped the golden kazan of a Volga Bulgarian khan into the Kazanka when collecting water. The registry office was opened in July 2013 to replace other registry offices in the city.
