The project consists of the initial WWII fortress reconstructed to serve the city’s purpose of an Astronomy centre. The functional distribution of specific areas has been designed to suit various educational programs (a polyvalent lecture hall, a chamber for digital projections of the Universe, exhibition areas), scientific programs (a telescope-equipped observatory, computer room, a scientific lecture hall), leisure programs (café bar, a terrace overlooking Rijeka bay on one and highland rear on the other side) and commercial programs (a lecture room containing scientific literature, brochures, audio and video data, optical instruments for observing the sky etc.).

In sense of shape, the complex has been architecturally composed by interpolation of the new auditorium into the existing fortress with an observatory. The formal solution in this case emits a specific semantic context. Inasmuch, a first time visitor notices independent accents in the observatory area containing a telescope, located within the observatory dome (the actual image of the Universe) and the oppositely placed new observatory located within a polyhedron (simulated image of the Universe) – as two significant and decisive contents for an easier framing of astronomy as a discipline and a better understanding of the world we are surrounded by in infinite distances.

In accordance, the new corpus of the observatory hall is shaped resembling a stylized meteorite – a piece of irregular stone, leaving an impression it fell from Space onto the Earth’s surface. More precisely, this part of the building is shaped as an uneven polyhedron, a geometrical shape bounded by flat surfaces that is polygons of ferroconcrete. Two neighboring sides meet with edges, and opposite edges meet in apexes. All spatial diagonals which hinge apexes on various sides of the polyhedron lie within this corpus making it convex. Within the corpus there is a semi-sphere of the projection dome and a theatrical auditorium.

Astronomical Center Rijeka won a prize at International Property Awards 2014 in category Public Service Architecture for Europe.
