Functional and aesteticly designed building with greatly organized programes connected with maritime with links to astronomical navigation and using planetarium and telescopes in educational purposes
The Astronomical Centre is housed in an extended military fort, a massive rectangular stone building with cylindrical corner towers. The northwest tower houses the observatory with a built-in telescope. At the top there is the movable dome of the observatory. The concept of the Astronomical Centre is based on the functional connection of the contents of the planetarium with other spaces of the centre and the observatory. Users of the centre can experience and see at the same time a simulated, but also a real picture of the universe that surrounds us with the MEADE LX 200 telescope, with a lens aperture 16″ (406.4 mm) with a maximum magnification of up to 800 times, in the dome and the new polyhedron planetarium with a projection hemisphere (diameter 8 m) and a theatrical auditorium. In the functional distribution of the planetarium space, by interpolating the new hall into the existing fort, the building is adapted to hold various educational programmes (polyvalent lecture hall, planetarium hall for digital projections of space appearance, exhibition spaces), scientific lectures (observatory with telescope, computer workshop, spaces for scientific gatherings), for rest and leisure (cafe bar and terrace with a lookout point towards the Bay of Rijeka and the hilly hinterland) and commercial programmes (thematic shop for books and brochures, video and audio materials, optical instruments for observing the sky, etc.).
