This picture was taken in Tula. There is the Kremlin in it. The Kremlin includes a church, a museum and a long wall with some towers. Some buildings were built in the 14th century. I really like this place because of its "ancient atmosphere". And I can feel it even through this photo.
Yes, you are completely right! There is a museum of Samovars in the square near the Kremlin. People from many countries go to Tula to visit it because all samovars of different times, shapes and colours are really worth seeing!
I have been to Tula a few times, two times as a toursit. I remember walking round the Krimlin and inside the main yard. I remember some volonteers or museum animator who were eintertaining the public with some folk dances and games. I guess somewhere near the Tula Kremlin there is a museum of Samovars!
