First-level sunken courtyard pictures

Quick answer：

A sunken courtyard, also known as a sunken garden, is a type of garden design where the garden is at a lower level than the surrounding ground. These courtyards are often used in traditional Chinese architecture to create a serene and private space. The pictures of a first-level sunken courtyard would typically show a garden area partially or entirely below ground level, with steps or a slope leading down to it. They often feature elements such as stone pathways, water features, and traditional Chinese landscaping.
