These photos of a hill covered in crosses show the amazing sight it has become. Photo: In 1831 an unsuccessful uprising against the Russian czar left many rebels dead.

Jonny Joo, 23, visits derelict malls, stations, towers and other places because they remind him of Silent Hill – a psychological horror video game which was made into a film. “When I first started exploring places, so many would remind me of the game. It was a world I was kind of obsessed with because of how dark and eerie it looked”, Joo said. His book, titled “Empty Spaces”, will feature 116 images and is being released this week.

Pictures of deceased people are seen inside a chapel at a cemetery in the village of Smoljinac, Serbia, October 25, 2016. From a distance, the cemetery in the eastern Serbian village of Smoljinac looks like a residential neighbourhood eerily placed among graves. But once inside the grounds, after passing a section with the usual stone slabs, visitors find rows of small bungalows painted in pastel colours. They have one or two rooms, large windows and ornate plaques – some inside, some outside – memorialising the deceased. These are the burial chapels of Smoljinac, cosy cabins with a furnished room inside, a storage place for wreaths and funeral paraphernalia, and the family crypt below. Some even have electric power inside. (Photo by Marko Djurica/Reuters)
