Real scene of an indoor sunken courtyard

Quick answer：

An indoor sunken courtyard refers to a courtyard that is located below ground level within a building. These courtyards can provide a green, serene space within the structure, often featuring plants, water features, and sometimes even a small pond. They are particularly popular in modern architectural design for their ability to enhance indoor air quality and provide a sense of privacy. The actual scene of such a courtyard would showcase the integration of nature with the built environment, often with a focus on the aesthetics and functionality of the space.
