The mysterious bashnya grifonov, sometimes known as the number tower is a truly unique sight – an 11 metre high, two metre wide brick tower covered in numbers. The tower itself is the leftover remains of the factory of the famous 19th Century pharmacist and alchemist William Pell – hence the local legend that invisible griffins nested there – griffins and alchemists make good lab partners don’t you know. The numbers were added in 1994 as part of an installation by Russian artist Alexei Kostroma and apparently giant eggs (presumably griffin) were installed in the top of the tower. They say anyone who can add up all the numbers on the tower in his head in one go will discover the secrets of the universe…get counting!
