A group of entrepreneurs in Turkey's southern province of Antalya, have installed a unique attraction called the "Upside down house" in the city, hoping to attract tourists. The idea of an upside down house attraction is not new, but has recently started to become widespread all around the world. There are already 12 of them in the world, with the 13th being opened by Turkish entrepreneurs in Antalya. Visitors in the Turkish model find that all the contents of the house have been flipped on its head, causing them to feel dizzy after their experience and even holding on to the furniture in the house to find their balance, said one of the project's entrepreneurs, Kaan Karahan, to Turkey's state-run Anadolu Agency (AA).The upside down house is at an angle of 25 percent with the ground, Karahan told AA, adding that 100,000 visitors are expected to visit the house per year. The visitors reportedly love taking pictures with the upside down contents of the house. "We think the upside down house is very important for alternative tourism. We are very happy about people's interest [in the house]," Karahan said.Only the second floor of the house is currently open to visitors, but its first floor is expected to open soon, with plans to further enhance the project in the future, according to Karahan.
