This fake medieval city was built in the suburbs specifically for the filming of the television series. There is a church, and a tavern, and a market square, and a city prison.
In fact, this is not just a museum, it is also three real objects: a hovercraft, an ekranoplan (seaplane) and a whole submarine "Novosibirsk Komsomolets". Visitors are not allowed on the boat and ekranoplan "Eaglet" due to poor technical condition, but you can wander around the boat, stare, touch it...
