For example, architectural (rather than agricultural) terracing also occurred on the island of Babeldaob in modern Palau in the Pacific Ocean.
The terrace is often pierced in the center by a tree, which along with the house cabin roofs and walls provides shade, and may be decorated with large flat ceramic bowls of fish and water lilies or by potted plants.
