Doges palace columns by paragianna75
There is a legend saying that when the noblemen wanted to convict someone they were sending him to pass a test that would prove his innocence or not.The test was to walk with success from one column to the next without losing the balance and stepping the ground just in front of the columns.But as you can notice in the pic, one of the last columns is built quite different than the others making that effort more than impossible sending all those poor men to prison or to death.
