The stated schedule is "every day from 10 to 16." The visit is free of charge. We need to go to the reception desk, they will call an employee.
But. Barely hit it. (It was at the end of March) At first, the museum was closed for Friday and Saturday. An employee was called on Tuesday, but he is not working... On Wednesday, before leaving, I still managed to get in.
There are posters with information inside the shopping center, and a small tomb inside the gray building. There are also a couple of posters about the Urartian burial near it. One original item, the rest of the copies found here (the originals were sent to the Erebuni Museum, I also recommend it).
The employee is not a tour guide, but a very interesting person.
