Kazan Kremlin is a true heart of the city. Built at the behest of czar Ivan the Terrible, it is the World Heritage Site and the only Tatarian citadel on the territory of Russia.
There is no other place where Russian and Tatarian cultures are blended together in such a beautiful and harmonious way.
The Kazan Kremlin includes many striking historical landmarks, such as the legendary Leaning Suyumbike Tower, the 16th-century orthodox Annunciation Cathedral, the Kul Sharif Mosque, the Spassky monastery, the Palace of the President of Tatarstan, etc. There is also a number of museums including the Museum of Islamic Culture, the Museum of Natural History of Tatarstan, the Great Patriotic War Memorial Museum and the Hermitage Kazan Exhibition Centre (a branch of the State Hermitage Museum in Saint Petersburg). Since the Kremlin is located on a hill, it offers fascinating views on the Volga and the city.
The place is very tidy and well-kept, and there is so much to see, you can spend up to a day there.
