The Transformation Hall is the latest 1000 sq. m. ETM space – an interactive exhibition about the human relationship with energy. In its centre, in a Faraday cage, two of the largest Tesla coils in the Baltic countries are installed, and on the side of the hall, the foundations of the historic chimney of the first public power plant of the city of Vilnius were opened, the exact location of which was not known until now.
The Transformation Hall was created to inspire interest in science and technology, to present exact sciences in an understandable and engaging way. Each exhibit consists of a historical narrative and an interactive challenge. After completing the challenge, you will generate energy, which will be converted into Quantums of energy, and you can exchange Quantums for souvenirs and a Transformation Hall Engineer certificate.
 
Liepkalnis Water Storage is one of the most interesting underground structures in Vilnius. Built in 1916, the hundred-year-old water storage facility located under the mountain belongs to largest water supply company in Lithuania “Vilniaus vandenys” and stands out for its unique structure and acoustics – the echo here repeats itself 5-6 times.
The reservoir was used until 1987, until now the strategic object of the city’s water supply system was closed and protected. From July 2023, it’s opened to the public. Energy and Technology Museum organizes guided tours, the new space is open for concerts, cinema and art – the impressive acoustics and the green outdoor area will eventually become a new event center.
Guided tours for groups from 20 people can be booked by phone (+370 5) 275 4312 or email via visitors@etm.lt.
