It is impossible to come to Kazan and miss the Kremlin. It majestically stands on a hill which, according to legend, was once home to the fire-breathing Zilant dragon, guarding the underground kingdom. Today, the Kremlin complex spanning across 150 thousand square metres, houses the residence of the President of the Republic, various administration buildings and the "Kazan Kremlin" Reserve Museum among others. In 2000, this architectural and historical site was added to the list of World Cultural and Natural Heritage sites of UNESCO https://visit-tatarstan.com/en/places/attractions/kazanskiy-kreml/
