Development of universal museums in 21st century

New trends in the museum practice of the beginning of the 21st century are explored. Emphasis is placed on the activities of the world’s largest art museums, which are often called «universal». These museums are traditionally located in the capital cities, have huge collections of works of art of all civilizations, they are visited by millions of people every year. It is noted that their modern development is characterized by such features as the increased presence in their hometown, the creation of branchs in other cities and regions of the world, intensive exhibition activities, an appeal to world-famous architects for renovation and expansion. It is characteristic that such museums, which are traditionally perceived to be quite conservative, nowadays demonstrate an orientation towards modern society, an involvement in its development and an interest in its hobbies.
