visited a small fortress/military museum

 The moat became dry.

wide angle view of the roof. (click to enlarge pictures)

Circular Rails enable wide angles.... 

 

magazine here means the storage for...

a model of the mini fortress.
Guns were install at the roof. 360 degree defence.

Historical events/sites/museums are good places to remind people

about searching & re-discovering ancestral roots

 Each of the small rooms were the sleeping room for several soldiers.
The five lower parts are last defence just in case enemy come into the fortress from the high walls.

Unexpected to see a Japanese sword there.
Probably captured from Japanese soldiers during the WWI or WWII?

I didn't know that there are wavy temperline at the sharp edge of Japanese sword (katana)

After the war, it has been used as music, model land, etc.

Annual heritage day / open day. Free of charge.

There is a cafe inside.
