After the works of 1838 the acceleration of the inclination continued for some years, after which it decreased to about a millimetre per year. Over the XX century, increases in knowledge and improvements in technical instruments, together with the involvement of conservation and government authorities, have promoted studies, research and even conservation interventions. Since 1988 the Tower has been closed to the public and a committee of experts is working to evaluate every danger likely to worsen the inclination of the Tower and to develop definitive measures to block, and hopefully to invert, the inexorable inclination of the monument towards the ground.
