Unsolved Mysteries From Around The World

Mysterious Staircase Of Santa Fe

Two mysteries surround the spiral staircase in the Loretto Chapel: the identity of its builder and the physics of its construction.

The stairway's carpenter, whoever he was, built a magnificent structure. The design was innovative for the time and some of the design considerations still perplex experts today.

The staircase has two 360 degree turns and no visible means of support. Also, it is said that the staircase was built without nails—only wooden pegs. Questions also surround the number of stair risers relative to the height of the choir loft and about the types of wood and other materials used in the stairway's construction.

The most mysterious place in Europe

Riese (German for "giant") the code name of the mining and construction project of Nazi Germany, started and unfinished in the Sowie Mountains and Ksiaz Castle in 1943-1945. It consists of seven complexes of the underground military facilities located in Lower Silesia, previously Germany, now territory of Poland.

There are more than 200,000 cubic meters of tunnels cut into
the Sowie Mountains, over an area of nearly 200 square kilometers, at the cost of 150 million marks and an unknown number of human lives. What did Hitler's construction specialists need the mind-boggling amount of 257,000 tonnes of reinforced concrete for?
