In the 9th to 12th centuries, noble estates around the (then) capital city of Kyoto frequently contained shinden gardens. The central component of this type of garden was a large pond located next to residential buildings. A brook that fed into the pond often passed underneath raised floors, connecting the buildings with the water. These gardens would also often feature islands and waterfalls.
Shinden gardens, however, are now a thing of the past. We only know of their existence from historical documents and some remaining ponds.
