Leaning Tower of Pisa "very slowly reducing its lean," say experts

Experts of the tower’s surveillance group, which monitors restoration progress, said the monument was “stable and very slowly reducing its lean” following 17 years of observation.

The 57-metre (186ft) construction straightened by 4cm (1.5in), according to engineering professor Nunziante Squeglia of Pisa University, who was quoted in Italian media reports.
