Museums play an important role in protecting and maintaining cultural heritage for future generations across the world. Many museums help in maintaining different culturally important objects for the public or tourists and several others have private collections which can be used by specialists, and researchers. A museum maintains a large number of objects and commonly concentrates on a particular theme such as natural history, science, local history, science, and many more topics. Public museums may arrange exhibitions that are also considered to be tourist attractions, and several other museums may attract huge numbers of foreign or local tourists which also creates more jobs for individuals.

The main aim of the museum is to collect, maintain, and display objects of cultural, artistic, and scientific significance for the research of education of individuals worldwide. Some visitors may only visit museums to study different cultures of different countries across the world. Large numbers of tourists visit museums to study or know about different cultures worldwide thus museums are also one of the main tourist attractions among visitors.
