The twin spiral staircase of Graz is located at the former castle (Burg) of the city. In German it is generally known as Doppelwendeltreppe or Zwillingswendeltreppe. It was built around 1500.
Decisions, decisions, which one should I take?
Tip: The entrance to this staircase is inside the inner yard of Graz Castle (Grazer Burg). The door hidden behind that tree depicted above is generally open for public. Don’t forget to have a look at the Roman tombstones immured outside the staircase.
