Visual Pyramid was built by an artist Juraj Gabor. Originally it served as an art construction for an exhibition and through it you could watch an hour long film about nature. After it served its purpose, the artist decided to move it to real nature and let people who take a hike to Sulov rocks enjoy it for free.
It's a great spot for taking unique photographs, but it's advised to go check it out on a week day as it attracts many lovebirds during weekends.
