Now, standing in the middle of this square we have a splendid view of the largest and most important church in the Christian world. The Church was started in the early of the 16th century and took over a hundred years to complete. Bramante, Raffaello, and Michelangelo all worked on it. The centerpiece of the church is the magnificent dome standing over 120 meters high. We shall now go into the church and climb to the top for some wonderful views of the city – so I hope you are feeling fit!The magnificent structure we are now passing is 300 meters high and has stood on this site for over a century. It stands as a proud example of the technological and engineering achievements of the 19th century France. It is said that the British planed to build a similar structure just a bit higher, but they only got as far as the first stage when – so the story go – the structure began to collapse.
