A lot has changed in Zagreb over the years, beautifully captured in this series of images by Ognjen Ivanović. The photographer has travelled across the city with old pictures and polaroids in hand, documenting how Zagreb looked then and now. The results are fascinating and also rather beautiful - just take a look at this slideshow of pictures to see what we mean.
