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.

All of them, except this small portion, had been decayed and gone.

Then, this tower began to lean. Because the lack of support pillars caused the ground to sink.


Major Restoration


In 1950-1955, the buildings and the stone walls of Matsumoto Castle underwent major restoration. These buildings were carefully dismantled and then restored in exact detail to their original condition. The original materials were reused as many as possible.
