The Leaning Tower of Pisa is famous because it does not stand to the ground.

That is correct! The Leaning Tower of Pisa is famous for its distinctive lean. It was originally planned to be a vertical structure but began tilting soon after construction started in the 12th century. The lean was caused by the soft soil and inadequate foundation on one side of the tower. Over the centuries, efforts have been made to stabilize and preserve the tower, including various restoration projects. Today, it still stands at an angle but remains one of the most recognizable landmarks in the world.

The statement you provided is partially correct. The Leaning Tower of Pisa is indeed famous for not standing straight vertically and leaning towards one side. It is a freestanding bell tower located next to the Cathedral of Pisa in Italy. The tower started to lean as soon as construction began in the 12th century, due to the soft ground it was built on.
