THE TOWER OF PISA

The Tower of Pisa is the campanille of the cathedral of the Italien city's of the cathedral of the Tower of Pisa, known worldwide for its nearly four-degree.                                                           
It's a third-oldest structure in the cathedral square (Piazza del Duamo).                    

The Tower of Pisa was built in 1740. It's a dessing incredibily. Surrended is inclined by a wall.
And it has 8 levels.                                                                                                                              
It's made of rocks and it was difficult to build.                                                                                   
Its 20'396389 m, it is also six metres high and it weighs 14'700 tonnes and there are 294 steps.

In my opinion, the views are very sastifacting, is exhausting to climb up because there are a lot of steps.
If you prefer, you can take the guide but it's more expensive, because the tiket costs 25 for person, but children don't pay.
Totally recommendable.
