When the museum is open, the system of "no free tickets" is implemented. A limited number of 5000 free tickets are issued every day. Visitors must queue up at the ticket office with valid documents (ID card, passport, student ID card, military officer's card, old age card, driver's license, etc.). ). Invoicing will stop at 16:30, and one person, one card, one vote (children under 1.4m can enter for free).
