High on Sveti Križ hill, Rijeka keeps its window to the universe: an observatory and planetarium in one place. Lean back under the dome as projected constellations wheel overhead, then step outside to a wide view over the city and the Kvarner Bay. On clear evenings the telescope turns the real night sky into the main show.
Come for an evening programme: afterwards the lights of Rijeka and the Kvarner glitter at your feet.
A small next-step selection from the same city.
