The leaning tower of Pisa
When the construction of the tower of Pisa began in 1173, not everything went smoothly. The tower began to lean more and more. The project was halted several times and the new floors were built straight, making the tower not only leaning, but also crooked. The leaning makes the tower very unique and therefore the tower has been a tourist attraction for years, bringing in a lot of money.
Experiment with music-making road stopped after one day
If a motorist drove the permitted speed on the N357 in Friesland, the Frisian National Anthem would be played at the correct speed. Unfortunately, the experiment was stopped after one day. Motorists drove extra fast to see how fast the music could be played. In addition, local residents heard all sorts of noises mixed up; the road not only caused dangerous situations, but also inconvenience.
