The book presents almost unknown and extremely valuable Islamic heritage in Croatia, which was comprehensively researched and interpreted by the authors; the historical layer of Ottoman monuments from the 16th and 17th century and the layer of contemporary Islamic architecture of the 20th and 21st century. Reasons for relatively unexplored and unrecognised Islamic heritage in Croatia lie in systematic and radical devastation of Ottoman monuments back in the first years of the Christian Reconquista at the end of the 17th century and ideological and religious antagonisms in the past, which resulted with the eradication of the remaining material fragments and suppression of the fact that the large part of our territory belonged to the world of Islamic civilisation, culture and art for more than a century and a half. Croatian territory was the westernmost point of the Ottoman and Islamic heritage in Europe; space of parallel contact, sometimes even overlap of Islamic artistry with the west renaissance from the other side of the border. This fact makes the topic internationally relevant and interesting in the European context and thus effort was put into a bilingual Croatian and English edition of the monograph. The book is the result of an almost ten-year-long research (terrain, archive, bibliography). It gained international success soon after publishing; it won the Ranko Radovic Award for the best theoretical book on architecture and the city in 2018.
