The Nizhny Novgorod Kremlin is a unique military engineering structure of the early 16th century and currently preserves the image of a medieval fortress: deaf turrets in several tiers, inaccessible walls with narrow slits of loopholes.
At the beginning of the XVIII century the Kremlin lost its military significance and turned into a monument of antiquity. In 1896, the Dmitriyevskaya Tower of the Kremlin, reconstructed according to the project of the capital's architect N. Sultanov, housed an art historical museum.
