1. The Spiral Staircase in the Taihung Mountains, Linzhou,China
The physical pain of scaling a cliff, without climbing gear, is worth the elevating experience that may never be encountered again. This 300-foot (91,5m) staircase along a mountain face in the Taihang Mountains offers the thrill of mountaineering without the danger. However, due to safety and health concerns, climbers are required to be under 60 years of age and have no heart or lung problems.

2. THE MIRACULOUS STAIRCASE

The Winchester Mystery House in San Jose, California, was built by Sarah L. Winchester, widow of the famous gun maker. The 160-room house was under constant construction for 38 years, until Winchester’s death in 1922.
Ms Winchester believed that the house was haunted by the spirits of those killed by Winchester rifles, and that only constant building would keep them from taking her life.
One of the many strange features of the house remains the staircase that leads straight to the ceiling!
3. THE HELIX STAIRCASE at Sisters of Loretta Chapel

The Helix staircase at Sisters of Loretto Chapel in Santa Fe, New Mexico, has legendary roots.
It is told that the Chapel was built without access to the choir loft where there was no room for a normal staircase, so the sisters prayed to St Joseph, Patron Saint of craftsmen, amongst others, for a solution.
A mysterious man, looking for work, arrived and built the spiral staircase without a centre support pole. He then left without being paid. The nuns believed the stranger to be St Joseph himself.
Later evidence points to the staircase as the work of French woodworker, Francois-Jean Rochas. Some still claim the staircase to be a miracle as it has no visible means of support, whilst others say the support is there, but just hidden from view.
