Leaning Tower closer than in Pisa, Italy. The foundation stone of the tower - the bell tower - was built in 1832. She suddenly tilted after prolonged rains. The cause was in the wetting of the soil and in the relatively narrow foundations of the building. It was later reported that the deflection was 70-75 cm. In 1997, a professional survey found that the tower was tilted from the vertical axis by 98 cm to the southwest. The handicap of the tower turned into a certain advantage - it became a tourist attraction.
An innovative idea is to identify points of interest with infotainments that serve visitors to obtain quick information. Point of interest, from English Point Of Interest (POI), we understand as a tourist or otherwise interesting place.
