The Republic of Tatarstan is a place with harmonious coexistence of different cultures and religions. Tatarstan is the embodiment of friendship between different religions and peoples, so the cultural heritage of the Republic is diverse and amazing. The religious and historical monuments, as well as architectural structures that form the ensemble of Kazan and the cities of the republic, create the unique and amazing image which remains in the memory of travelers forever. The image of Tatarstan is organically composed of several historical layers, starting from the time of the Kazan Khanate to the present day. It is complemented by modern buildings which attract tourists as much as the historical ones. After all, there will come time when the modern buildings built before our eyes at the beginning of the 21st century will be considered old.
