A couple of days ago we went past the biggest and the longest viaduct in the world. It is in Millau, South France. The highest point on the viaduct is nearly 400 metres high. It can fit the Eiffel Tower in it.
Yesterday (Monday 13th) we went to Pisa and saw the Leaning Tower of Pisa. The construction of the Leaning Tower of Pisa was begun in 1174 from the architect Bonanno Pisano and was finished in 1350 by Tomnmaso Pisano. The height is 58.63 metres high. The weight of the Leaning Tower of Pisa is 14.452 tonnes.
The maximum slope from the top to the centre of the base is 5.22 metres. The Leaning Tower of Pisa leaned an average of 1.2mm a year until 1993. After 11 years of rebuild the Tower opened on the 15th December 2001 with an inclination reduced of 38 centimetres.
