Preikestolen or Prekestolen, also known by the English translations of Preacher's Pulpit or Pulpit Rock, is a famous tourist attraction in Forsand, Ryfylke, Norway. It consists of a steep cliff which rises 604 metres (1982 feet) above Lysefjorden, opposite the Kjerag plateau, with an almost flat top of approximately 25 by 25 metres (82 by 82 feet).Via Reddit.

The authorities have opted not to install fencing or other safety devices as they felt it would detract from the natural beauty of the site and the fact that fatalities at the site are extremely rare, despite having approximately 200,000 visitors each year. Furthermore, there were concerns that fences or other devices might encourage dangerous behavior such as climbing onto the fences. It should also be noted that it is a policy from Norwegian authorities that "we cannot fence in all nature in this country", and this is supported by the Norwegian population who are generally more accustomed to "dangerous nature" of their country than foreign tourists.
