I have only just stumbled upon Jan Kempenaers' photographs of the extraordinary and rather wonderful 'spomeniks' - or monuments - in the former Yugoslavia. Apparently these structures were built in the 1960s and 1970s in Tito's Yugoslavia to commemorate the Second World War. Between 2006 and 2009, Jan Kempenaers explored the region using a 1975 map of the memorials. The resulting pictures have been published as a book: Jan Kempenaers (2010) "Spomenik", Roma Publications.
Above and below is a selection of the images - see more here; read a review of the book by Guy Lane and an article by John Bailey.
