The main entrance to the observatory and museum is an aluminum-plated, complex, ellipsoid building reminiscent of an alien space ship. On the first floor of the space ship, the museum’s reception room is located in a glass aquarium, while a café and cozy conference hall are located on the second floor.
In the great telescope tower, the main telescope has been installed; measuring 80 cm in diameter, it is one of the largest public telescopes in Europe.
The museum’s main accent is the ellipsoid glass observation deck, measuring 18 m wide and 36 m long and made of openwork metal pipes and glass. This impressive, futuristic glass and metal structure rises above the forests surrounding the museum and creates the impression of a space ship that has just landed.
Mitnija was awarded a gold medal for the project in the Lithuanian Product of the Year competition.
