 The Turba is one of the few areas in the Shirvanshah complex where we actually know the name of the architect who built the structure.In the portal of the burial vault, the name "Me'mar (architect) Ali" is carved into the design, but in reverse, as if reflected in a mirror.Some scholars suggest that if the Shah had discovered that his architect inscribed his own name in a higher position than the Shah's, he would have been severely punished.
