The main branches of education and popularization were determined by the Commission on Preservation of History and Art Monuments of the Trinity-St. Sergius Lavra. On February 23, 1919, P.A. Florensky guided the first excursion in the Sacristy. In 1921, excursions were systematic and the Museum received three thousand visitors. The records of the Commission of 1923 mentioned: “The Museum workers often had to interrupt their work and act as …tourist guides. … Though this rule did interfere with their research, the members of the Commission willingly fulfilled this duty regarding it as the principle meaning of the Museum activity”.

The members of the Commission were outstanding people of the early 20th century. Now, knowing the biographies of Yu. A. Olsufyev and P.A. Florensky, we can say that their role in the Museum organization was determined not only by the historical circumstances but by the activity of their souls. The priorities in the education work changed depending on the political and ideological directions.

In the 1920s, excursions were the main form of the educational activity. The Excursion Bureau was responsible for that work. It included not just the Museum workers.

As early as the late 1930s, the Museum paid much attention to preparing guides: training excursions were conducted by the senior research workers and department managers; lectures were delivered by the teachers of the Moscow higher educational establishments; consultations on art and history were given by the leading specialists: A.V. Archikhovsky, S.V. Bakhrushin, V.I. Lebedev, N.N. Sobolev, I.V. Zholtovsky.
