A leaning red-brick tower, the oldest Orthodox church on the Volga and a row of museums in the old barracks, all inside the Kremlin walls.
The Söyembikä Tower is Kazan's symbol: 58 metres of red brick in seven tiers, leaning almost two metres off true.
It is named for Söyembikä, the last queen of the khanate. Each tier has its own legend, the best known being that she leapt from the top rather than marry Ivan the Terrible.
Beside it, the white Annunciation Cathedral of 1562 is the oldest Orthodox church on the Volga, with restored frescoes inside.
The former barracks hold the Hermitage-Kazan, the Natural History Museum and the Cannon Yard. Look out for the Zilant, the winged dragon on the city's arms, which is everywhere.

Stand at its foot and look up to see the tilt.

Excavated workshops where the Kremlin's cannons were cast.
Look out over the Kazanka to the new city.
