A Remaining Piece of Pillars
The total weight of the castle is about 1000 tons. To support such a heavy castle 16 wooden pillars (5 meters long for each) were used inside the stone foundation. Under the stone foundation slender logs were laid for preventing the castle from sinking and additional piles were installed into the ground for a landslide.
