A pleasant park on the island, where in ancient times there were fortifications protecting the city from the sea.
Fragments of stone loopholes, artillery positions, and defensive ditches are still preserved.
All this historical past is buried in the lush greenery on the ground. Above, above the ground, from all sides - the city of Tokyo of the 21st century.
A pleasant place for a leisurely stroll, photographing the panorama of the city.
