If you want to experience calm tranquility combined with visual profoundness, visit the Old Jewish Cemetery when you are in Prague. You are only able to see around 12,000 tombstones that are visible, there are layers upon layers of graves that contain the bones of around 100,000 people in total. Since graves were dug up and reburied so many times, the effects of time have left thousands of crooked and angled tombstones. There is limited area to navigate between some of them because of how they have moved. Hours can be spent viewing the tombs that are piled one on top of another and looking at tombstones that are hundreds of years old.
