The rate of incline was sharpest during the early part of the 14th century, although this didn't dissuade town officials or the tower designers from moving forward with construction. Unfortunately, the building continued to settle, sometimes at an alarming rate. Engineers tried to make another adjustment, this time in the fifth story, only to have their work interrupted once again in 1278 with just seven stories completed. Soil under the foundation continued to subside unevenly, and by the time work resumed in 1272, the tower tilted to the south - the direction it still leans today. Until recent years tourists were not allowed to climb the staircase inside the tower, due to consolidation work.īut now the leaning Tower of Pisa is open again and it is one of the most popular tourist attractions in Italy → Book a Hotel or check our → Visit Tower of Pisa page.The tower sat unfinished for nearly 100 years, but it wasn't done moving.
