In Foucault’s conception, space and power are closely related, and spatial discipline is a crucial idea. Through the analysis of military camps, prisons, hospitals, schools, etc. in 17-19 centuries, Foucault proposes that discipline, as an art of distribution, has the characteristics of enclosure, partitioning, function, and rank. There are three main approaches to discipline: hierarchical observation, normalizing judgment, and examination. He also puts forward the idea of “panopticism”, which he thinks has highly universal potential and has been extended to every corner of society. Although Foucault does not discuss museums in detail in his research, it is still possible to find a place for museums in his conception of spatial theory. The museum, as a public cultural space, is an important part of Chinese socialist culture, and also an important place to enhance national ideology and cultural identity. This paper combines theoretical analysis and case study and takes the Capital Museum in China after the pandemic in 2020 as an example to make an in-depth analysis of the disciplinary practices embodied in the museum today. The paper points out that there exists discipline in museum space and the disciplinary role of museums is mainly reflected in the following aspects: the architectural structure of museums, the spatial location of exhibits, the planning of visiting routes, the arrangement of the staff and the norms and regulations of museums.
