During our fantastical trip around Japan we saw many architectural delights including the castle at Osaka.
On a clear sunny day, it stood proud against a perfect blue sky.
The castle is one of Japan's most famous landmarks. It's built on two raised platforms of landfill supported by sheer walls of cut rock, using a technique called Burdock piling, each overlooking a moat.
The central castle building is five stories on the outside and eight stories on the inside, and built atop a tall stone foundation to protect its occupants from attackers.
