Double spiral staircase, an architectural and engineering marvel is silently standing within a public building in old town of Graz, Strya, Austria. Completed in 1438 CE, under guidance of Holy Roman Emperor Frederick III, Burg of Graz was expanded by Frederick’s son, Emperor Maximilian from 1494-1500 CE. When reopened, officials and civilians marvelled at “Doppelwendeltreppe”, or “Double Spiral Staircase” that travelled two floors to top of tower. This architectural masterpiece of 1499 CE, has often been interpreted as a symbol of eternity. Graz people call it “stairs of reconciliation”. If you go separate ways, you will at some point reunite.
