Mosque, Rijeka Islamic Centre

Arguably the finest contemporary building you are likely to see in Rijeka, if not anywhere on the Adriatic, the city’s stunning new mosque looks more like a science-fiction illustrator’s idea of a base on the moon than any public building you might have so far seen in Croatia. Built to designs by abstract sculptor Dušan Džamonija, it takes the form of a silvery fragmented dome – as if a Chocolate Orange is being pulled slowly apart so you can see the segments sliding away from each other. With a boldly geometric minaret corkscrewing upwards to one side and the blue Adriatic in the background, it’s a genuinely thrilling sight.
