After the 100 year hiatus, Giovanni

After the 100 year hiatus, Giovanni di Simone stepped forward in 1272and began to add four more floors to the tower. He actually managed to cause the tower to lean over more when he tried to compensate for the original lean by making one side of the upper floors taller than the other.
In 1284 construction was halted again, this time because of the Battle of Meloria, in which the Pisans were defeated by the Genoans.
In 1319 the 7th floor was finished. The bell-chamber was added in 1372, and then the tower was left alone until the 19th century.
In 1838 Alessandro Della Gherardesca, an established architect, dug a pathway near the base of the tower so that people could see the intricately crafted base. The tower began to lean even more as a result, likely due to the decreased amount of support available within the soil.
