Double Helix Staircase in Ljubljana Castle, Slovenia by dinah1

This is an interesting old double helix spiral staircase. A double helix staircase is formed by two independent helical stairs in the same vertical space - the way up intertwined with the way down so that you do not have to pass people going in the opposite direction on the staircase.
