It is situated beside Starosyanovo village. Russian and foreign tourists often lose the possibility of visiting this place, barely, because they don’t know about it. But it was really here where the stone for the first lime rock Moscow kremlin was quarried (that is why Moscow has ‘White-Stoned City’ epithet, although its current walls are red). Though, ‘Syani’ (short for Syanovo: ‘Syani’) isn’t attributed only to history, the original digging culture with its own traditions and mindset has been developed in here.
