Courtyard Dry Landscape

Quick answer：

A dry landscape garden, also known as a Zen garden or karesansui, is a type of Japanese rock garden that uses carefully placed rocks, gravel, or sand to represent a natural scene, typically a mountainous landscape or a water feature, in a minimalist style. These gardens are designed to evoke a sense of tranquility and to be meditative spaces. They are often found in Japanese Zen Buddhist temples and traditional homes.
