Before anything, make sure you don't get plagiarized though here is my short note:
Over 5 million people visit the leaning tower of pisa. People visit the leaning tower of pisa because it is an important monument for the city pisa. It is also a important reminder of the difficulties of engineering and architects built in the past.
I am not sure if this short note is enough, but I hope it helps because you've helped me a lot!
