A gorgeous place immersing in the atmosphere of industrial facilities of the last century. An ideal example is how old buildings and mechanisms can not be destroyed, but turned into an interesting tourist site. If you are without children and do not know Lithuanian, there is not much point in going to the basement hall (and paying 3.5 euros extra) for the show. It is better to spend it on leisurely inspections of other halls. You can use the online audio guide.
An interesting museum with several expositions on different levels. Downstairs there are the remains of the first Vilna power plant, which was located in this building, just above there are two expositions with the decoration of the Soviet period, and then there are printing presses that can and should be touched, even higher there is a room with many experiments for children and adults. And that's not all! I haven't been to the museum yet after the renovation, perhaps there are a lot of new interesting things there.
A decent museum, several expositions, an audio guide in several languages (including Russian for free)
, a large playground for children including a slide with a speed meter. There aren't many people.
