Visočica (Шаблон:IPA-sh) (also known as Brdo Grad (Шаблон:IPA-sh) (Bosnian: Hill Town) is a hill in Bosnia and Herzegovina famous as the site of the Old town of Visoki Шаблон:IPA-sh as well the 2005 claim that it is an ancient man-made pyramid. It is 213 metres high. The idea that it constitutes an ancient artificial edifice was publicised by Houston-based expatriate Bosnian author Semir Osmanagić, but scientific investigations conclude that it is a natural geological formation known as a flatiron.
The Old town of Visoki was a famous medieval royal castle town during the fourteenth century, located in Visoko Шаблон:IPA-sh, Bosnia and Herzegovina. The first mention of the town was on 1 September 1355, in the charter "in castro nosto Visoka vocatum" written by Tvrtko I of Bosnia while he was a young ban. The town appears to have been abandoned before 1503, as it is not mentioned in the Turkish-Hungarian treaty that was established that year. In the year 1626 Đorđić mentioned Visoki among abandoned towns.
Visočica hill became the focus of international attention in October 2005, following a news-media campaign promoting the false idea that it is actually the largest of a group of ancient man-made pyramids.
Scientific investigations of the site show there is no pyramid. Additionally, scientists have criticised the Bosnian authorities for supporting the pyramid claim saying, "This scheme is a cruel hoax on an unsuspecting public and has no place in the world of genuine science."
