8 .   T H E S P I R S T A I I N G D A R R O U B L E L C A S E A Z BURGGASSE 3 The double spiral staircase in Graz is also called the twin staircase , it was built in 1499 - 1500 during the reign of the German king and later the emperor Maximilian the First by an unknown master and she is the castle of Graz in the stair tower and is one of the main examples of building art . This creation of the Late Gothic period was built very carefully and with a great love of detail , which can be seen thanks to the patterns and precision of the details . In 1506 , 2 gravestones were placed in the facade of the staircase , which in itself should have meant a close connection at the turn of the Middle Ages and the Renaissance . Who actually built the ladder and is not known , but suppose that there could be Peter Parler , and directly over the production of parts worked a whole series of masons , which is witnessed by special signs on the stones .
